Hi Everyone

I’m really in a Jam! My dead line is coming up, and Cisco was no help.

I am programming a Cisco 506e PIX Firewall

Outside configuration  is DSL using Dynamic IP Address

Internal Address for the PIX Firewall is
Datacenter network is Network which is working fine.

My local branch “Datacenter is able to get on the internet.” Because they are on the same segment as the PIX and the Cisco router, But my WAN can not!!!

None of my remote office cannot brose the internet

My Question is, how do I get my remotes offices Computers to brose the internet threw the wan

My IP Routers Are

My Networks are

I have a Total 40 People on the Wan that Need to the Internet

Example: PC Configuration

Working PC
IP Address:
Gateway :       “Cisco Router”
DNS1:    “Windows 2000 Server DNS”
DNS2:       Pointing to PIX

Not Working PC Example
IP Address:
DNS1:  “Windows 2000 Local Backup DNS server”
DNS2:  “Pointing to PIX”

>DNS2:       Pointing to PIX
PIX will not act as a DNS cache, so you can remove these entries..

What is the default gateway setting for the router @
Does it point to the PIX?

ip route

Do all the other remote routers point to this router as THEIR default gateway?

You must propogate the default gateway across. Do you run any dynamic routing protocol?

It does not look like a PIX configuration issue, but more of a routing issue with the remote sites...

Yes, The default router is
Now seems it could be a DNS Issue. After doing tests on it!

I enabled ICMP to ping Addresses
I am able to ping "Cisco" etc

Ok, I will remove the PIX from DNS2
What would I put in its replace! Since, the first DNS is for my internal DNS.

It seems the Browsers are resolving dns names.

Unless you have a secondary DNS, you can leave it blank, since you want all your internal clients to use your internal DNS and it should have either forwarders or root hints.

>It seems the Browsers are resolving dns names.
That's a good thing, no?

If they browsers are resolving names, can they browse sites?
If not, then I still say it is a routing issue, because the dns resolution comes from the internal dns server.
