[Astlinux-users] Config NAT Loopback

[David K. <da...@ke...>]

Is it possible to configure NAT Loopback on its own... ie, without opening
NAT->LAN for all sources?

I have a problem where my employer's VPN is hijacking DNS so name
resolution for my internal hosts is always getting routed to the VPN's
supplied DNS which will not resolve to my internal IP address, so traffic
is getting sent to my external IP address.

Loopback works, I can set a port number to forward but I don't want to open
the firewall port to any external client, only to a client on my internal
network.

It looks like I can set Source IP to e.g. 192.168.1.0/24 and that will
setup the firewall rules.  But is that the best and/or safe way to do it?

Thanks
David
