Forward traffic from WAN to WAN

Post by nikola.vuckovic » 25 Oct 2017, 21:56

Hi,
I have one server which I've moved to a completely new location. Server had SAT with dedicated IP used only by this server. Now I need to make sure all clients having old IP can connect to new IP so what I want is to forward all traffic coming to old IP to new IP.
To clarify:

Firewall: 1.1.1.1
Server: 1.1.1.2

New server IP: 5.5.5.5 (this address is on public internet, not in firewall)

What I want is to forward all traffic coming from WAN interface to IP 1.1.1.2 to 5.5.5.5 via same WAN interface.

I've tried with SAT + Allow and although rules are triggered correctly and correct WAN routed and gateway is used, I get no response from the destination server. Destination server is otherwise accessible via internet (no limitations).
Any ideas?
Thanks
//Nikola

You need a SAT + NAT rule, otherwise the respnse will be sent from new server directly to client and will not be allowed by neither the clients firewall or the client.

Hi Anders,
I've tried that as well but it didn't work. Then I figured out I had a rule in the middle breaking SAT+NAT.
Now it works when I have moved two rules on top and next to each other :)
Thanks for help
