I have configured an ASA 5510 to be between an internet router and a cisco
switch. I have 3 servers in my inside network which users access from outside
and these servers also have public addresses, my inside user can connect to
the internet,surf the net and I can also pull down mails from my exchange
server via the internet, BUT MY REMOTE USERS CANNOT ACCESS THESE SERVERS FROM
THEIR REMOTE END.
Below are the configs on both the router and ASA for someone to please help me
check and look what I did wrong.
Please help me.
