PIX and ISDN connection filters

[rrgg]

Hi all.
This is my PIX configuration, I need deny all not interesting traffic like UDP 137 - UDP 138 - TCP 139.
I try to do it but when I add deny access-list role the ICMP traffic doesn't work.
I need to add this role on PIX.

HI.

What exactly did you do?

You can try something like this:
access-list frominside permit udp any any eq 53
access-list frominside permit tcp any any eq 80
access-list frominside permit tcp any any eq 443
access-list frominside permit tcp any any eq 25
access-list frominside permit tcp any any eq 110
access-list frominside permit tcp any any eq 53
...
access-list frominside permit icmp any any
access-group frominside in interface inside
