Accessing both private and public IP address on DMZ
I imagine this solution is out there but after browsing posts for an hour I can't come up with it.
Below is my network and were using an ASA 5550 8.2.3.
static (dmz,outside) 22.214.171.124 10.10.12.10
What I need to be able to do is from the inside access a server on the DMZ via both the 10.10.12.10 address as well as the 126.96.36.199 IP. I can get either or to work but cannot get them both to function at the same time. Ideally it would be even better if when you connected to the 10.10.12.10 ip address it returned the 188.8.131.52, but that's not a 100% necessary.
This scenerio works like a champ on the PIX and 6.3.5 code via the static (dmz,inside) 184.108.40.206 10.10.12.10 dns command.
Re: Accessing both private and public IP address on DMZ
I am not sure if you got an answer to this one. But in 8.2.x and earlier releases of ASA its not possible. But in 8.3.x and later releases it is possible or at least i have seen it work. Please refer the below link for more information on that:
I was able to connect to either IP address from the internal networks to the dmz without issue. It's a little messy but atleast it's a solution as eliminating a internal name server from a billion dollar a year company isn't. I didn't create the mess I just inherated it
