New ASA5505 configured with ASDM. Tried to get the config running on 8.03 and the current 7.23.
What I want to do is setup a list of our Static IP's and allow only them to access a Terminal Server using only the TS ports specified in a TCP Service Group. The config I have looks very much like the config I have in another ASA5510 which is working fine.
When I try to connect from the defined static IP static1 via the RDP client I can see it being block in the syslog.
Deny tcp src outside:static1/31856 dst inside:xxx.xxx.xx.xxx/3389 by access-group "outside_access_in" [0x0, 0x0]
I am at a loss as I think I have the Static NAT and ACL correct.
Thanks for any help
Regards,
Brad

Ah sorry Brad, my bad. Do this
access-list outside_access_in extended permit tcp object-group YPMStatics interface outside object-group termservports
12-17-2007 11:04 AM
Hi Brad
In your ACL, you permit YPMStatics hosts to establish connection from termservports to host temptermserv on termservports. But from port is a randomly created port so you shouldnt specify it in ths case. Do the following modification
no access-list outside_access_in extended permit tcp object-group YPMStatics object-group termservports host temptermserv object-group termservports
access-list outside_access_in extended permit tcp object-group YPMStatics host temptermserv object-group termservports

I did make the change (had it this way when I tried the 8.0.3 image).
It now says:
access-list outside_access_in extended permit tcp object-group YPMStatics host temptermserv object-group termservports
But I still get the syslog error
Deny tcp .... by access-group "outside_access_in"
Thanks for the help.

Brad

Thanks husycisco, that worked like a charm I can get some sleep tonight.
Cheers!
