AJ: Cant surf when using proxy

[ajarina]

I have a PIX 501 connected to a DSL line and heres the scenario:

If i connect the PIX inside interface directly to a workstation, I would be able to surf and access the internet witout a problem.

But if ill use a proxy to connect between the PIX and the local network, I cant get the workstation to connect to the Internet. My proxy is using wingate and in the local network I have 3 different networks that can access each other. Here is somt troubleshooting that i tried.

From the proxy, I can ping to the inside networks. I can also ping to the PIX inside IP address also but I cant ping to the next hop address in the outside(gateway of PIX). Is there some issue with Wingate or some routing that I need to do? Please advise. Thanks.

Do you add routes onto the PIX pointing to the intenal networks, with the proxy as the next hop?

Have you got any access-list placed on you PIX ?

i.e. access-list inside permit tcp host any eq www

Let me know...

im not hosting a web server so i dont use access-list for www but i do have this to check connectivity.

access-list inbound permit icmp any any

access-group inbound in interface outside
