how to forward traffic from lan to public ip of that server?
source 10.10.10.0/24
destination 10.11.110.200/32
but i want to DNAT when connection want to go via LAN to forward to destination WAN?
source 10.10.10.0/24
destination 1.1.1.1 - server side WAN IP (there i dnat already)
If I undestand correctly, it’s two subnets behind same router, which has 1.1.1.1 as public address and some port(s) should be forwarded to server 10.11.110.200. And it should work from both internet and other LAN subnet 10.10.10.0/24. It that’s the case, it should work, you just need correct dstnat rule (so definitely no in-interface=WAN) and firewall that doesn’t block it (default one wouldn’t).
