Title: 1:1 nat problems, outbound is working but not 1.1
Post by: deserted on March 04, 2021, 10:53:50 AM

Hello,

I'm new to OPNsense and can't wrap my head around why 1:1 NAT is not working but outbound is.
We see that the internal ip of 10.1.4.11 translates to the public ip .
But the states are just getting SYN_SENT:CLOSED

all tcp <publicip>:63359 (10.1.4.11:63359) -> 172.217.21.132:443 SYN_SENT:CLOSED
all tcp 172.217.21.132:443 <- 10.1.4.11:63362 CLOSED:SYN_SENT

Anyone know things we can try and look for? Or more information you need.

Bit late on this, but I assume you have added an inbound firewall rule apart from just the 1:1 NAT?
