Please point me to another post if it has the answer.
We have a customer that has two internet sources that connect to the Astaro as follows. The Astaro is an ASG220 running 7.503.
Internet -> Astaro -> LAN
Internet -> 3rd Party Firewall -> DMZ -> Astaro -> LAN
The 3rd Party firewall only purpose is to provide access to two specific destinations via tunnels and not any general internet traffic. It also does not have any routing capability built into it. The problem this presents is that I have to setup the Astaro to NAT all LAN traffic bound for this 3rd Party Firewall from the LAN to the DMZ IP (and back again). Needless to say, I am having trouble with this as I keep getting Invalid Parameter errors.
I cannot change the devices and I cannot move the tunnels.
Any assistance would be helpful. I would discuss what I've tried, but I feel like I've tried every iteration except the one that would work.
Attached is an image of the setup in case my description is confusing.
Thank you,
Jason
