OPNsense has NAT Problem

[pleibling]

Hi,

i have two Interfaces (Server vlan0.33 Tag 33 and Security vlan0.50 Tag 50).

Both are allowed via AutoNAT - Internetconnection from Servernetworks works via NAT - but Security not, the settings looks same.

Here are the Firewallrules.

I did not look into your rules, but as a general rule: NAT alone is not sufficient to be able to create a connection.

For LAN, there is a default "allow to any rule", for self-created interfaces, you have to create a rule yourself. Remember to block inter-LAN access, though.

Are you sure SERVER is running? The last rule for SERVER only allows ICMP, while for SECURITY any ipv4 protocol is allowed...
