RE: Could someone help me !
There is a few things going on here. Everyone that has replied that I have seen so far, has missed a major thing. Source Port, and Destination Port swap for the return packet. Scenario #1, You want to browse a webpage. Your PC: 10.192.168.1 Web Server: 10.0.0.2 Your PC sends out a packet, this packet will look partially similiar to this layout: Source Address (Where it came from) : 10.192.168.1 Source TCP Port (Random number 1023) : 31000 Destination Address (Where it is going) : 10.0.0.2 Destination Port (Well-known service port) : 80 When this packet comes to the webserver, it looks.. "My IP Address? Yes. Port number? tcp/80. Do I know what that port is? Yes, pass it to Apache." Apache then looks, "Source 10.192.168.1, new session. Source port 31000." It adds : 10.192.168.1,31000 to a table of active connections, and preps a packet with the information requested. It will look like this: Source Address (Where it came from) : 10.0.0.2 Source TCP Port (Random number 1023) : 80 Destination Address (Where it is going) : 10.192.168.1 Destination Port (Well-known service port) : 31000 The packet is then sent through the network to your PC. Your PC looks at the packet, "For my IP? Yes. What port? tcp/31000. Do I know what that port is? Yes, I just sent a request in Netscape window #2 on that port to the source address of this packet." Pass it to Netscape, which opens the file. This process continues, allow with TCP ACK packets, since this is a tcp session, until that file is loaded. This is also done in several threads at once, to load your webpage faster. If this still confuses you, draw a picture on a big piece of paper.. two computers.. several arrows going left and right, and write it out visually. Just try to remember that for the scenario listed, your PC always uses tcp/31000 (only in this scenario, it is a random number between 1024-65536).. the webserver always uses tcp/80. Whether these numbers are "Source" or "Destination", depends on the direction of the arrow. 1 More attempt.. if the first didn't work. Think of it like an airplane flight, round trip. You have a source airport, and a destination airport. On the way home, they are swapped. Vancouver to Toronto: To Toronto, your ticket (packet) is like this: Source Airport (where I'm leaving) : YVR (just like an IP, it is unique) Source gate : Domestic, A30 Destination Airport (Where I'm going) : YYZ Destination gate : Domestic, I43 On the way home, for the sake of this example, your flight happens to use the same gates (since they do in a tcp session). This is a round trip ticket, so I'm not leaving from Vancouver, I'm going to Vancouver. Source Airport (where I'm leaving) : YYZ (just like an IP, it is unique) Source gate : Domestic, I43 Destination Airport (Where I'm going) : YVR Destination gate : Domestic, A30 Just an analogy to see if it helps.. some people get it, some don't. That's the way I thought of it at first, and now it's just second nature.

You answered your own question. Sessions are distinguishable from each other because they have different source ports. 80 is a well-known port that clients use to get to Web servers. The client uses what is known as an ephemeral port -- a port number that the software makes up for the current session. It is a high number that won't conflict with a well-known port. To expand on this further, ports below 1024 are considered "privileged", and many ports are "well-known" meaning that certain applications will be "listening" on them. For example, BGP-speaking routers have a socket listening on TCP port 179, and packets sent to a destination port of 179 are handled by the BGP protocol process of the router. Similarly, web servers have a socket listening on port TCP 80, name servers on UDP 53, mail servers on TCP 25, etc. A list of the well-known port numbers as well as many other useful numbers of things having to do with this industry is in RFC 1700. A machine seeking to initiate a TCP connection chooses a random port above 1023 as the source port. When it begins the connection, it opens a socket in order to listen for a reply, and the three-way handshake is established between this random source port and the specified destination. A trace of the other side of the connection would show the source port/IP and the destination port/IP combinations reversed. The other end's source port will match this end's destination port and vice-versa. This is how NAT overload or PAT keeps track of sessions. When an inside IP begins a session with a destination, the NAT router re-maps the source port to one of its choosing, and keeps a database of the outside port to inside IP mappings. When the router detects a reply on a given port, it uses this database to identify to which inside IP the reply should go, and translates the (inside) destination port/IP to match that of the sending machine. This is necessary to have multiple sessions carrying different content to different inside machines and the same outside destination. The command "show ip nat translations" will display this. Say two inside machines both begin to browse the Yahoo web site at the same time, but one requests a stock quote and the other an auction. The PAT router sends two streams to Yahoo's IP address but from two different source ports. Yahoo treats them as two different connections because the source ports (assigned by the router) are different, even though the source IP of the router's NAT pool may be the same. When the return data streams come back, the router looks at the incoming port numbers (its destination, Yahoo's source) and directs the streams to the proper inside port/IP NAT pairs. Otherwise, the machine requesting stock quotes might wind up displaying auction data, as the router would have an ambiguity in its translation table as to which machine the stream should be translated. By keeping track of its outside source port to inside IP address mappings, the router can avoid this problem. Extended access lists can filter on both source and destination ports, to filter traffic by type. This isn't perfect, as it is possible to move a traffic type to a port which isn't filtered. Many non-Web applications use TCP port 80 as a destination in order to get around corporate firewalls which are likely to block many ports but generally allow web access. -- Jay Hennigan - Network Administration - [EMAIL PROTECTED] NetLojix Communications, Inc.

Re: Diff between rfc1483 and rfc1577
RFC 1483 was obsoleted by RFC 2684 RFC 1577 was obsoleted by RFC 2225 RFC 2225 Describes Classical IP and ARP over ATM. It appears to deal with LANE (LAN Emulation) and treats clients as if they are part of the same broadcast network. RFC 2684 seems to deal with just carrying multiprotocol traffic over ATM, either by using different Switched Virtual Connections or the same SVC. Just by reading the abstract you can kind of see the differences between the two... I would assume that the they get more into detail the more you read into them. I just skimmed the abstract to get the above. -- Kevin - Original Message - From: "huan" [EMAIL PROTECTED] Newsgroups: groupstudy.cisco To: [EMAIL PROTECTED] Sent: Saturday, September 30, 2000 10:43 AM Subject: Diff between rfc1483 and rfc1577 They both work on IP over ATM, 1483 is classic IP, and 1577 is IP over ATM, but what is the real diff between them?

Re: My impressions of Juniper from the test lab
Dave, We can test and compare apple with oranges in that respect. Why?. GSR internal architecture is based on shared bus/cpu while GSR using distributed, cross-bar architecture. Therefore, to perform the test fairly you should load the M-xx with PIC's and the GSR with 8, 12, or 16 lincards and verify the performance. Also, could you please clarify what type of GSR LC that you test against?. Cisco has 3 generation of line cards, their OC48/QOC12-POS is able to forward raw data throughput up to 4 Mpps, which I don't think Juniper can accomplish that with fully populated box. - Ihab --- David Wolsefer [EMAIL PROTECTED] wrote: The juniper M20,M40, and M160 are serious routers in the core IP routing world because they simply outperform the 12000GSR. Although I did not test them against the latest and greatest GSR, we ran tests with the M40 heads up against a few older model GSRs. Needless to say, the Juniper is very impressive. We took a smartbits and started loading up the links up to OC-48. The M40 handled the load extremely well at wire speed with no packet loss. The GSR, on the other hand, started dropping packets at about 50% of that load. Does this mean the performance couldn't be improved on the GSR? No, not at all. These GSRs were not tuned at all.

Re: A golden apple: Frame Relay
Correct me if I am wrong...It's a layer 2 protocol. It takes the place of say Ethernet (another layer 2 protocol) It supports layer 3 protocols such as IP and IPX and is supported by layer1 protocols such as B8ZS or AMI "Bradley J.

EXTENDED ACL for distribute-list
Hi all, Could someone shed some light on how to use EXTENDED ACL for distribute-list? I'm trying to allow only 10.1.1.0/24 route to be distributed by eigrp 90. Below is config and debug ip eigrp output. I thought ACL 110 is a bit "relaxed" but should have allow the 10.1.1.0/24 route to be distribute out. But it got DENIED. ACL 10 worked. Initially, I had "access-list 110 permit ip 10.1.1.0 0.0.0.0 255.255.255.0 0.0.0.0" which I thought would be the most specific. But this didn't work also. I found the URL below from Open Forum: http://www-1.cisco.com/cgi-bin/Support/OpenForum/dispnewqa.pl/6352 If anyone have some good link on this topic, please kindly send them in! Any comment welcome!

Re: Learning PIX??
Syngress (www.syngress.com) is coming out with a Cisco Security reference guide.. there is a chapter dedicated to PIX in it.. It covers the PIX very well... As far as learning it, your best bet is to get your hands on one. PIX 506 (low end) is relatively cheap compared to the 515 UR. And as Hao mentioned, check out the cisco website.. loads of information there.. Keep in mind that PIX is a firewall, Checkpoint, Netscreen, Raptor and other firewall products are built off the same concepts.. configuring them is the different part... Hope that helps Russ..

Re: Learning PIX??
The great thing about Cisco hardware is it retains its value quite well. With that in mind I would suggest buying a used one from Ebay. Play with it until you are satisfied and then resell it at very close to (or the same as) what you paid for it, essentially costing you little or nothing to get PIX experience !!! - Original Message - From: JD [EMAIL PROTECTED] Newsgroups: groupstudy.cisco To: [EMAIL PROTECTED] Sent: Saturday, September 30, 2000 10:19 AM Subject: Learning PIX??
