Re: [LARTC] UDP port 1194 marking/routing problem
Wang, That solution does not suite me: ip route add default via $DEFAULTGW dev eth1 ip route add xxx.xxx.xxx.xxx/32 via $ANOTHERGW dev eth0 Because only UPD 1194 has to be routed via eth0 to OpenVPN server IP, everything else to same Ip has to go via eth1. Any ideas?

Example: ip route add default via $DEFAULTGW dev eth1 ip route add xxx.xxx.xxx.xxx/32 via $ANOTHERGW dev eth0 The second, send all your traffic to IP xxx.xxx.xxx.xxx via eth0. When your box acts as your intranet's gateway, you can SNAT or MASQUERADE on eth0, like iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE. For you openvpn configuration, you can either bind openvpn to eth0's ip, or let system chooose the IP, in most case the output interface.

[LARTC] Router for the two diffent networks
Hi folks, I have the Linux (Slackware 8.1) router and I use it to replace hardware router ( for example CISCO). This router is for only external IP addresses: I got 6 IPs from my ISP and of course to use them I made router on Linux box. My scheme is: Internet connection form radio modem | eth0 - | Linux box| - | eth1 | switch| || - -- | FW1 | | FW2| - -- || Local network All network connections use ext IPS except local network. Everything works just fine. So my question is can I put two extra network cards to my Linux box and use the same PC as router for the second Internet connecton? Or do I have to use second one Linux box for it? eth0 and eth1 routing between first ISP IPs and eth2 and eht3 is routing between second one IPSP IPs?

[LARTC] I need some help with u32 filter
Hello, This is my ADSL connection : ADSL 512k/256k | eth0 | Linux box aka fw | - | eth1 the firewall has smtp and pop3 servers running (I have no spare PC for email server, byt just for home use it is OK) Could somebody check my script please, I'm bit confused of ports 25 and 110 on eth0 and imq0. tc qdisc del dev imq0 root tc qdisc add dev imq0 root handle 1 htb default 10 r2q 100 tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1 htb default 10 r2q 100 tc class add dev imq0 parent 1: classid 1:2 htb rate 500kbit burst 15k tc class add dev imq0 parent 1:2 classid 1:10 htb rate 468kbit ceil 500Kbit burst 30k prio 0 tc qdisc add dev imq0 parent 1:10 handle 10 sfq perturb 10 tc class add dev imq0 parent 1:2 classid 1:20 htb rate 32Kbit ceil 400Kbit burst 15k prio 1 tc qdisc add dev imq0 parent 1:20 handle 20 sfq perturb 10 ## tc filter add dev imq0 parent 1:0 protocol ip prio 100 u32 match ip sport 25 0x classid 1:20 Is it enough to have only sport 25 on download link or I need the dport as well? ## tc class add dev eth0 parent 1: classid 1:2 htb rate 250kbit burst 15k tc class add dev eth0 parent 1:2 classid 1:10 htb rate 218kbit ceil 250Kbit burst 30k prio 0 tc qdisc add dev eth0 parent 1:10 handle 10 sfq perturb 10 tc class add dev eth0 parent 1:2 classid 1:20 htb rate 32Kbit ceil 250Kbit burst 15k prio 1 tc qdisc add dev eth0 parent 1:20 handle 20 sfq perturb 10 ## tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip sport 25 0x classid 1:20 tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip sport 110 0x classid 1:20 The same question on eth0 (upload link) Is it enough to have only sport 25 and 110 on upload link or I need the dport as well? ## Thank you very much in advance Remus ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Re: [LARTC] u32 filter rules
Hi, Maybe I gave no examples what I want, sorry. I have the outgoing trafic rules for the 3 local IPs (some rate, ceil and etc) and I can browse or do whereever from Internet side speed. But for the local net of these 3 IPs (ports smb, smtp and pop3) I would like to have 99Mbit speed. I use the htb_ 0_8_3 script on eth1. I can limit by IP for example 156k downlink but if I want to have for the same IP 99Mbit for local connection it does not work. The same situation I have for my imq on eth1 to limit incoming trafic as well. ADSL 512k/256k | eth0 | Linux box aka fw | | eth1 Local net of the 3 PC Any ideas/examples?

[LARTC] u32 filter rules
Hi folks, Can I use in the same parent but for the diffrent classes u32 filter rules: 1) filtering by ip address (very low speed only for the Internet) 2) filtering by port (smb, smtp and pop3) for the local connection Thanks in advance Remus ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
[LARTC] HTB classes, ceil and prio
Hello, I'm looking some recommendation how to configure htb. I have ADSL 512k/256k connection at my home for the 3 clients PCs and one Linux Box like firewall. Network looks like usual: ADSL connection (eth0) - | firewall | - (eth1) local network I would like to divide Internet connection like this: Download eth0 (512K) SSH/IPSec rate=256k, ceil=512k and prio=0 (it can be used from the local PC1 or PC2) PC1 1.2.3.1(local ip) rate=170k, ceil=512k and prio=1 PC2 1.2.3.2 (local ip) rate=170k, ceil=512k and prio=1 PC3 1.2.3.3 (local ip) rate=170k, ceil=512k and prio=1 SMTP server (exist on firewall) rate=64k, ceil=128k and prio=2 or better 1 Do I understand right if some of PCs (PC1or PC2) use SSH/IPsec it gets speed from 256k up to 512k if it not in use. Two anothers PCs and SMTP server share 256k between them. Is that right? What speed they get each? Upload eth0 (256k) htb/imq SSH/IPSec rate=128k, ceil=256k and prio=0 (it can be used from the local PC1 or PC2) PC1 1.2.3.1(local ip) rate=80k, ceil=256k and prio=1 PC2 1.2.3.2 (local ip) rate=80k, ceil=256k and prio=1 PC3 1.2.3.3 (local ip) rate=80k, ceil=256k and prio=1 SMTP server (exist on firewall) rate=64k, ceil=128k and prio=2 or better 1 If I'm not correct just correct me, please. Is it enough to have only one class or more? I know that running htb on external eth, htb cannot see local ip addresses. Can I mark them with the iptables and use it with the htb? Or do I have to make htb rules on my local eth1 as well?

[LARTC] about Linux router
Hi folks, I got a new one Internet connection (Wireless) and to have more then one external IP I need a router. I don't want to a new Cisco or whoever router I would like to do it on Linux box. I prefer to use RedHat 7.3 for that and what I have to install on that Linux box (iptables, ip route and etc ) ? Two IP's will be for my FW's and one for router (like default getaway for my FW's).

[LARTC] HTB configuration
Hi folks, I'm new in HTB (CBQ too). I want this scenario for my Internet connection: local IP 1 have to have half speed of internet connection (for incoming and receiving as well) local IP 2 another half of internet speed (for incoming and receiving as well) So if one of IP 1 or 2 doen't use connection to internet he get a full speed (like borowing) Sorry for my question but I really don't know how to do it. I tried to read HTB guide but cannot understand everything yet. Many thanks in advance Remus
