PPPoE & ACLs

[r-lemaster]

Cisco PIX Firewall Version 6.3

I recently enabled PPPoE and now my ACLs no longer permit incoming traffic to my public hosts (Outgoing traffic is fine).

I tried disabling 'ip audit', changing my static statements from 'interface' to the IP address, I even tried 'permit ip any any' and traffic still can't get through. The ACLs still show 'hitcnt=0' even though I'm hammering it from proxify.com and ShieldsUp.

I get nothing from 'debug packet outside', but when I run a capture it shows a lot of incoming requests in hex. When I import it into Ethereal, it shows a whole lot of incoming traffic, so it doesn't appear to be filtered by my ISP or my CPE.

For troubleshooting purposes, the Public address to my web server is <A HREF="javascript:newWin('http://74.2.65.94/')">http://74.2.65.94/</A>

My PPPoE config:

ip address outside pppoe setroute

vpdn group pppoex request dialout pppoe

vpdn group pppoex localname [MYPPPOEUSERNAME]

vpdn group pppoex ppp authentication pap

vpdn username [MYPPPOEUSERNAME] password *********

Hi,

HI,

The access lists are not bound to the outside interface .

Hence u need to add

access-list PUBLICHOSTS permit tcp any interface outside eq www

access-group PUBLICHOSTS in interface outside

rajbhatt- You ROCK!

How could I have forgotten to apply the ACL..?

I didn't need the other line;

access-list PUBLICHOSTS permit tcp any interface outside eq www

I think because I already have;

access-list PUBLICHOSTS permit tcp any host eq www

THANKS!!

Do you mean 'access-list PUBLICHOSTS permit tcp any interface outside eq www '?

I added it per your suggestion.

This is good for PPPoE?
