welp, if that IP address on your Linux firewall isn't right for the outbound interface, what is your IP address for that network? your routing table doesn't appear to have anything else in there...

ifconfig eth1

you can access the net from the firewall correct? and did you check the route on the clients?

RijilV:

All of my internal clients can access the internet perfectly through the firewall. My firewall can ping all of the internal clients perfectly, but I can not do ANYTHING (ssh, ftp, www, NOTHING) from that firewall out to the internet... QUITE weird. my ifconfig for eth1 was posted a couple of messages ago.

Mara:

I did it, and it deleted this time, but it is still not working.

Then you try to ftp to any Internet server from the firewall, what error do you get?

ftp: ftp.microsoft.com: Host name lookup failure

But I do not believe it to be a DNS problem because I resolved ftp.microsoft.com on another computer (207.46.133.140) and tried to ftp to that, and it worked. I cannot believe it may be a DNS issue. any idea where to go with that?

________ UPDATE

It can't be solely a DNS issue, because I still cannot ping the internet from my firewall, I cannot ping my external address, and I cannot ping local loopback. BUT I can ping the internal network...

It amy be a DNS failure. Do you have /etc/resolv.conf? And do you have your DNSes inside?

I doubt it is a DNS issue, because I cannot ping IP addresses OUTSIDE my network. The DNS info is in /etc/resolv.conf, and I cannot even ping the DNS servers, BUT all of my internal PC's resolve names just fine THROUGH that firewall, with the same addresses.

I am leaving work now (been SSH'd into my box), will be home in an hour and will check this for your suggestions. Thanks for taking all the time you did.

When you return home, write what happens when you ping one of your DNSes.

Sorry I didn't get back to you yesterday, had something come up. My brother actually fixed it, he said I was missing some TCP and UDP rules. Haven't had a chance to check to see what he did.

Thanks again for your help!
