RE: 2600 router - critical situation
This happened to me last week. It turned out to be a problem with the router resources. When you downloaded the IOS image it should have informed you what the minimum Hardware required to run the image is (Flash and RAM, 2600 default 8/32). After upgrading the flash, there is not an IOS image, so tftpdnld, as recommended by others, is your friend. I was loading the high crypto image (Which is Huge 11MB) and had neglected to upload the RAM to 48MB from its standard 32MB. At this point you should download a smaller image file from CCO and perform the tftpdnld with the smaller image. The symptom I had was that the router would self corrupt the image while trying to "self-decompress" and like you, my upgrade session was completed successfully. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Ravi Kumar Sent: Tuesday, February 06, 2001 11:00 PM To: [EMAIL PROTECTED] Subject:2600 router - critical situation hi friends I am in deep trouble yesterday i downloaded 12.0 IOS into my 2610 router from my TFTP server. downloading was successful. in fact i deleted old version while upgrading. after that my router is not booting at all. what to do? please help me. bye ravee Get free email and a permanent address at http://www.netaddress.com/?N=1 _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

NAT on 1605 with DHCP on Ethernet0
Dear Group Study, I have recently upgraded my Cisco 1605R to work on my cable connection to IOS 12.1.5T. I am finally able to negotiate an IP address via DHCP, now comes the tricky part. I wanted to implement NAT overload, "? Translating to interface's address: As a convenience for users wishing to translate all inside addresses to the address assigned to an interface on the router, the NAT code allows one to simply name the interface when configuring the dynamic translation rule: ip nat inside source list interface overload If there is no address on the interface, or it the interface is not up, no translation will occur. Example: ip nat inside source list 1 interface Serial0 overload " After adding all the appropriate commands I am still not able to pass traffic, I get an encapsulation error message when I do a debug all. Configs to follow. All possible debugging has been turned on Cisco1605# 18:22:26: CBAC Pak 2B062CC Saved sockets (192.168.0.35:1868) (207.46.130.26:80) tcp 18:22:26: S seq 1766696184(0) 18:22:26: IP: NAT enab = 1 trans = 0 flags = 80 18:22:26: CBAC Pak 2B062CC Saved sockets (192.168.0.35:1868) (207.46.130.26:80) tcp 18:22:26: S seq 1766696184(0) 18:22:26: NAT: i: tcp (192.168.0.35, 1868) -> (207.46.130.26, 80) [12299] 18:22:26: NAT: Allocated Port for 192.168.0.35 -> 204.210.242.88: wanted 1868 got 1868 18:22:26: NAT: s=192.168.0.35->204.210.242.88, d=207.46.130.26 [12299] 18:22:26: IP: s=204.210.242.88 (Ethernet1), d=207.46.130.26 (Ethernet0), g=207.46.130.26, len 48, forward 18:22:26: IP ARP: creating incomplete entry for IP address: 207.46.130.26 interface Ethernet0 18:22:26: IP ARP: sent req src 204.210.242.88 0010.7bdf.337c, dst 207.46.130.26 ..

Re: Can't Ping Local Serial Interface of 2610
Title: Re: Can't Ping Local Serial Interface of 2610 After adding the Frame-relay Map statement, as suggested by several people, I was able to ping the local serial Interface. I then created the interface as a Sub-interface and attempted to use the Frame-relay map command and received the "You should use the Frame-Relay Interface-dlci" command from the router. When the Tnterface-dlci command was applied to the sub-interface (s0/0.1) IP traffic began passing back and forth on the serial link. I also had to add the appropriate static route to the default gateway, as suggested, so other clients on the development network (192.168.1.0) would know where to send traffic destined for the test network (192.168.3.0) or the Intermediate network (192.168.4.0). Routes had already been setup on the routers, but the default gateway did not know about the 192.168.4.0 network until I added the static route. After adding the route all traffic successfully was passed from all clients to the Test network via the intermediate successfully. I understand now why I had to assign the Map statement to the global interface, so that layer Layer 3 knows which layer 2 interface to use, what I am still a little confused about is why the command changes when applied to a sub-interface to Frame-relay interface-dlci instead of Frame Relay Map IP. I appreciate all responses they all helped me to troubleshoot and understand the Frame Relay technology successfully, thank you.

RE: can we NAT the destination IP using IOS's NAT nature? [7:7050]
>If yes, can you show me how is the command look like? >>Hi, >>I guess you can config a static nat mapping >>and reverse the inside and outside interface. Mike, Try this instead, ip nat inside source static tcp 192.168.0.100 25 25 extendable This statement will allow mail to your rfc1918 addressed mail bridgehead server. With Cisco's implementation you can actually redirect ports to different output ports unlike most Linksys and Netgear cable/modem routers, have fun and secure your mail realy! The only difference from what you are asking is this is on a port by port basis, I am not familiar of a way to do full 1to1 NAT to virtual IP. Also I have not found any documentation supporting the ability to add "Conduit"(Pix, similar to ACL)statements or access-list's to these statics so use them at your own risk. HTH You can use a secondary address if you need "Virtual addresses" I beleive, I have tested with secondary's on the internal site but not the external.
