PIX 501 Help needed with simple HTTP / HTTPS config

Archived from groups: comp.security.firewalls (More info?)

Walter,

Thanks a million for taking the time to check my 'config'.

Are you suggesting that my config should look like this (below)? Can
you predict whether I'll destroy the VPN (which is in use by 10
employees) by loading the suggested config? (I'm not asking you to take
on any liability, just wondering what to prepare for if it does explode
on me)...guess I could back it up first. Here's your copied suggestion:

"""Yup. It's messed up.


name 192.168.4.192 WEB
object-group service HTTPHTTPS tcp
port-object eq www
port-object eq https


access-list outside_access_in permit tcp any interface outside

Thanks again! I really appreciate the help on this one.

Thanks again.
The VPN is working like a charm and has been for two months now. I'm
suprised myself. What happened here is my friend/Cisco expert passed
away, so I'm supporting products that he suggested, but can't support
now that they have arrived.

I only edited the IP schemes and domain info in my config file post, so
the fact that RCMSWEB is not defined could be leftover from when I
tried to define a route to it in the PDM console. I thought it would be
pretty straightforward to route all HTTP/HTTPS/FTP traffic to a
specific inside IP address (RCMSWEB), but it may not be. Perhaps I
should state what I want to accomplish overall, then you can recommend
if the config you sent to me would apply to my situation?

I need VPN for Terminal Services, inbound HTTP/HTTPS/FTP traffic routed
to webserver, inbound SMTP traffic routed to Exchange server, and
outbound HTTP for internal workstations. This should be easy, right?


I'll make sure the config file I posted is complete and repost it if
not.

Thanks for your continued help on this one! If you have other sources
for easy configurations on this firewall, please let me know.
