Route Problems with a Socks Proxy Server

Linux Red Hat 5.0 Multi Homed Proxy server.
Socks5 Proxy server installed
SocksCap32 TPC/IP shim run on client PC’s
Internal NIC address =

Internal Network Sub’ed into 2 Networks seperated by Routers and a T1 superpath.  Proxy server is on subnet (Router address is  Other subnet  is

External NIC address = (Connected to a Cable Modem and Road Runner) Road Runner upstream router is

Current problem : Internal clients can not connect to host for e-mail or when running “Socksified”.  The server refuses the connection.  External address browsing works fine.

When you try to ping or at the console you get “Network is unreachable”

Have tried :

Route add –net  result=“Network Unreachable”
Tried route del “on almost all entries and the Route Table comes back the same after reboot”
Tried changing DomainName in network file to “” (Was result=no change

Current etc/sysconfig/network


Current etc/sysconfig/static-routes

eth0 net netmask gw
eth0 net netmask gw
eth1 net netmask gw
eth1 net netmask gw

Current Output when “route” is run

You don't have route to localhost (lo0). I recommend adding it with netcfg (startx as root->networking icon of control-panel) and verify you have "lo" interface defined... It's address has to be

Anyway it would be better to instruct socksified clients no to use socks on the local network: you save a lot of cpu time...

Good luck

You are right; however, the reason I do not want to hit activate on it is that the IP address is blank.  Here is how it reads :

Interface       IP address      Proto   OnBoot  Active
lo                              none            inactive
eth0    none    yes     active
eth1      none    yes     active

When I try to edit to lo line it states that the local loop back can not be changed; however, if I hit activate what ip address will it try ? Thanks !
I've heard things like this... Always is due to some missing information... Just compare in /etc/sysconfig/network-scripts the definition of ifcfg-lo and ifcfg-eth0. Maybe the first has some data missing...
