PIX 506E, What am I doing wrong w/ my Configuration

[BlownOut]

Trying to get inbound/outbound access. I can ping 192.168.1.1 but that is all. Here's the config, Thanks!

You're not allowing any traffic out except tcp with source and destination ports equal 80. Probably not what you had in mind.

Start by removing "access-group inside_access_in in interface inside" and see what you have. Your outside acl allows all icmp, so ping should work as well as tcp & udp traffic. Then you'll want to trim the outside_in ACL as well.

Thanks lgarner,

I have removed the "access-group inside_access_in in interface inside" and I am still am not getting out. How should I define my ACLs and what should I trim in the outside ACL?

 

[lgarner]

Well, it depends on what you want to do. Right now you're allowing all TCP, UDP and ICMP, which doesn't leave much that's *not* allowed.

The default for a Pix is to allow everything out and only responses to come in. For example, you should be able to surf the web from the inside without messing with ACLs.

Recheck your "route outside" statement to make sure it's pointed to the ISP router. It looks like it might be mixed up with the subnet mask, maybe it's ok.

There might be something else... it'll come to me eventually.

Regarding ACLs you should remember is that at the end of every ACL there is an implied deny all. So when you have an ACL, you better have it completely set up, or something will not function the way you plan. So far it looks like your inside_access_in ACL allows TCP connections but nothing else. Maybe you should either remove it, or change it to permit IP. Although maybe I'm wrong and the pix treats TCP and IP as a protocol suite instead of individual protocols.

Also, you should change your telnet password from cisco, as that is a security risk.
