ASA 5505 Outside -> DMZ web access

Unanswered Question
Feb 1st, 2012
User Badges:

I have a server in the dmz and I cannot access it via port 80 from the web.  I can ping the public ip without any problem but for some reason web and rdp cannot be accessed.  The web server on the inside interface is working fine.


Anyone have any ideas?

Hello,


Are you able to ping 192.168.60.250 from the ASA?


Can you ping 192.168.60.220 from the server?


Please provide the following;


packet-tracer input outside tcp 4.2.2.2 1025 2.2.2.19 80


Regards,


Julio

Does not look like any issue with config still want to confirm.


Thanks

Here are two traces I did this morning. The capin is pre-nat on the guest

interface and the capout is post-nat on the outside. I attempted to reach

the server on port 80 from 66.54.184.254.


ARLASA01(config)# sh capture capin

12 packets captured

1: 02:27:21.032331 802.1Q vlan#198 P0 66.54.184.254.51336 >
