two routing tables
 
I want to set up two routing tables for my linux router. one table i want it to use all the time. and the other table i want it to use when a certain web site is trying to be accessed. how do i set this up.

What are you trying to accomplish? If you're wanting to create a blackhole for a certain website, just block access to it with iptables (or set a host entry pointing it to 127.0.0.1 if it's just for that box). If you're wanting to take an alternate path to that website, do route add <website IP> <nexthop IP>

well i have sorta a odd configuration and am having trouble with a website that i visit. the web site uses a kebros login and will only auth for 1 ip range. i have 4 wans that get load balanced though 3 daul wan routers. 2 wans for for each router and then an other daul wan to load balance them. i have one of the routers on the same group of ip addresses. so i want to direct all traffic to my.website.edu to 172.16.62.1 instead of the default gw 10.16.60.1. the linux box that i am using has 3 eth cards in it. eth0 is set up for testing on the wan right now with ip address 10.16.62.241. then eth1 is the card i want to direct all traffice to my.website.edu to. and eth2 is local

as says sigsegv you just need to say your linux, that you want to go to my.website.edu throught 172.16.62.1

route add -host my.website.edu.ip 172.16.62.1

Good luck!

when i use that scheme, i get an error "SIOCADDRT: No such device"

here is the cmd:
Code:
route add -host 169.237.x.x 172.16.62.1

here is my current routing table:
Code:
Kernel IP routing table

What IP do you have on 172.16.62.0/29? It thinks you're not on the same network as 172.16.62.1 (and if you're above 172.16.62.6, it's right)

fugzi 12-03-2004 06:02 PM
the ip is 172.16.62.3 for the linux box with the same mask
