Internet Sharing but behind firewall

LordHendrix · 06-01-2006, 10:46 PM

Code:

<internet> 
    |
    | 
<firewall>
    |
  <hub>
    |
<internet sharing server>(2 LANCARDS)
           |
           |
    <workstations>

1. the Firewall is using Squid.Proxy.Stable10 allowing only http_port 80, ip 192.168.1.1. so listening on 192.168.1.1 port 80.

2. Internet Sharing Server is Linux i have used for sharing:
echo "1" > /proc/sys/net/ipv4/ip_forward
/sbin/iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

My question is without using proxyserver settings on workstation how can i access internet? is it possible?
thanks in advance

you can add a transparent proxy on the server if you wish: http://www.faqs.org/docs/Linux-mini/...rentProxy.html
