Please assist!

I did Remote access LAB , the remote should be ok due to i succeed to connect with internal user , however with user from domain server i failed.

I checked the "fetch" tab, i succeed to fetch , i found something that might be problematic.

I had to set Static NAT to my ldap server via smartdashboard in order to communicate between my MGMT to my LDAP that are separated to two different networks (LAB environment , i had to separate them in order to get to my real internet so i be able to do First Time Wizard).

however the current situation is , that my GW is trying to communicate with the LDAP through his STATIC ip address and not his real ipv4 . -(They are directly connected to each other)

when i send ping from my gw to my server using the real ipv4 ; 10.10.10.1 i get a replay,
and when i send ping to his static nat ip address i get destination host unreachable,

the only thing that i could think of is that probably my GW is looking for this address through his external interface (which have the same network address as my static nat ; 160.30.251.0) and not through his internal interface.

I'm confused .. please assist me if you could see where did i wrong?

Thanks

You could try a traceroute to see exactly where the connection is failing.

See man traceroute for details.
