I have a pix 501 protecting my webserver and email server. Access to these servers work great....IF the user is either a)behind the firewall or b) connected to our LAN outside the firewall. No one outside our "domain" gains access. My logs show the following:
deny tcp src outside:a.b.c.d/4495 dst inside:172.110.107.20/80 by access-group "outside_access_in"
But the way I interpret my rules, I am allowing "any" network to reach through on that server. Any help would be appreciated.
