Since the t1n1wall forum has closed, I'm sorry to ask you a question here.
I've been used Smallwall, but it doesn't work on new server nor supports TLS 1.2. So I've conversion the rule to the t1n1wall.
It works good with only outbound nat firewall.
But, if I use 1:1 NAT for the servers as before, the NAT will not work at all, all accesses from the outside will not be possible, and the server itself will go to the outside with the local IP as it is.
I've found a title with a similar issue in past forums, but I can't read the article.
If you have any solution or hint, I would appreciate it if you could let me know in a hurry.
As a precaution, I deleted 1: 1 NAT and Proxy ARP and re-entered them, but they ended up in the "unparced nat rule".
