PIX 525 Help

I'm trying to get access for a server (Webserv3) in a DMZ from the internet. This is the first server I'm trying to get to from the outside. Also I'm trying to limit some of the PC's on inside networks from the internet. I think the problem is with the ACL but I'm not sure. Please respond here I'm not near my mail much.

Re: PIX 525 Help

in your acl outside access in, you only allow ftp to webserv3. add a line for tcp port 80 to allow web traffic. does it run a ftp daemon? have you been able to connect to it from the outside?

New Member

Re: PIX 525 Help

I have a ACL

access-list outside_access_in permit tcp any host XX.XX.XX.55

that references the server I'm trying to get to from the outside. I have not been able to get to it from outside but I can see it from inside.

Hello James -

Re: PIX 525 Help

Thanks for the reply.

This example uses conduits instead of access lists I thought conduits were replaced with access lists? Is there an updated artical? Should I use conduits?

James

Re: PIX 525 Help

access-lists are the future. conduits still work, but might be unsupported in a future version. you access-list look fine - I missed that permit tcp any line.

Aha - try this - I think your access-list applied to the dmz is wrong. Try removing it. I think your source is any, destination is xxxxxx.55, and it needs to be flipped - you want to allow source of xxxx.55, with destination any
