Hi everyone,
this is my first post in here so if I do make any mistakes apologies before hand. and thanks for spending time to read it out.
I got a problem with a ASA 5505 8.3 with DMZ settings,
At first I could not get the DMZ working at all as no connection to outside or from outside, and for some reason 1 of the servers has started to work and still have no idea why and how but having the exactly same issues with the second server.
Got a inside, outside and dmz interface
inside : 192.168.1.1
dmz :192.168.2.1
network object dmz-fbsd-bart: 192.168.2.2 static to XXX.XXX.XXX.71 Works fine
network object dmz-fbsd-itchy: 192.168.2.4 static to XXX.XXX.XXX.73
Cannot ping/access to outside or from outside however can access it using public IP from inside with a very high latency i.e ssh session login can take upto 20 seconds to prompts for password,
sh run is pasted as below
tried all on the net but no success missing something but What?
If you could help it will be greatly appreciated as it started go through my head and in a stage of nothing makes sense anymore.
