[praks25]

hey all,
have a question about outbound traffic from a high level interface to a low level interface.
for some odd reason the pix is not allowing any outbound traffic on any port except icmp (ping)
there are no explicit denies or any rules to hinder outbound traffic and it is true that the pix is configured by default to allow outbound traffic.
i have set nat to nat (inside)1 0 0
and global to global (outside)1....and a dynamic range of address. The nat id and the global id are the same.
could someone please hlep me with this one.
there are 3 routers on the inside but only one is directly connected to the pix and that one has it's gateway of last resort set to that of the pix.

maybe i'm missing something.
any help is appreciated
here's the running config

HI.

> nat (inside) 0 access-list acl_in
> access-group acl_in in interface inside
Do not use the same "acl_in" for different tasks.

Anyway, that is what currently blocking outbound traffic:
> access-list acl_in permit icmp any any
> access-list acl_in permit ip 100.100.0.0 255.255.255.0 10.90.100.0 255.255.255.0
> access-group acl_in in interface inside

Hi yizhar,
could you please elaborate on the access list and access group problem
I changed the icmp access list id to 100 and also added a new access group statment to identify id 100 with the inside interface, which means acl_in is now only used with the nating statement used while VPN'ing in.
i still can;t access the web
please advice
thankyou
