PIX Config. problem

Does anyone see anything wrong with this config. ? I just recently had to switch ISP and got only one IP from my new one. Since then, internet access has been sporadic at best and I cant seem to figure it out. Simple config for the most part other than port redirection to a single internal host for smtp, pop3, and www. Thanks for any help.

Re: PIX Config. problem


Does it help if you remove the VPN?

Do yu want to try to config split tunnelling for your internet traffic if possible ?

Re: PIX Config. problem

No. Everything is the same as it has been for a couple of years. The only thing that has changed is I changed ISP and only got one external IP to use. So, I changed the outside interface IP, changed the static translations, and changed the conduits to point to my internal server that hosts smtp, pop3, and www. That is when my problems started.


Re: PIX Config. problem

I would suggest that you convert your conduits to access-list first and check if this sorts out your problem. Mixing conduits and ACL’s is not recommended as the ACL’s will always be executed first.

Also clear translations with command clear xlate after the change and save with write memory.

Also here’s a good document on converting conduits to ACL’s by Bill Donaldson of GIAC Organisation.

Hope this helps and let me know how you get on.

Re: PIX Config. problem

The access-lists are only applied at the crypto map.

Shouldn't have any bearing on my conduits.
