This only guarantees your WANip:8100 will map to 192.168.0.113:81, and doesn’t address whether or not dns resolution is correct. I would also be weary of using port numbers on wikipedia’s known ports list, as some ISPs will filter those upstream. The last thing is that your router may not want to hairpin that traffic, so if you’re not coming in from the outside it might not be a valid test.
Conceptually it’s fine, but I 100% expect, in the fullness of time, I’ll accidentally post in one not thinking about it since I pretty much exclusively operate from the firehose feed. Until there’s a little more tooling around it (like, if I could mark a community as ‘read-only for me’) , I think strict/aggressive moderation to enforce that rule is kinda problematic.
