Server not appearing in Game List

[Zenarcane]

I swapped broadband providers a few days ago and since then I can't get my dedi to post to the server list.

I have 29600-29602 forwarded in the router to an internal firewall (PF Sense lab segmentation) and that has a NAT rule that forwards it to the actual server. I have packet capture from PF Sense that shows it's sending out, and the replies from Valve's server so that traffic is getting through to the server:

172.16.3.2.26902 > 162.254.196.67.27018: [udp sum ok] UDP, length 84

11:51:38.961585 00:0c:29:50:c2:42 > 00:0c:29:7d:43:7e, ethertype IPv4 (0x0800), length 78: (tos 0x0, ttl 121, id 5794, offset 0, flags [DF], proto UDP (17), length 64)

162.254.196.67.27018 > 172.16.3.2.26902: [udp sum ok] UDP, length 36

11:51:47.560844 00:0c:29:7d:43:7e > 00:0c:29:50:c2:42, ethertype IPv4 (0x0800), length 126: (tos 0x0, ttl 64, id 8928, offset 0, flags [DF], proto UDP (17), length 112)

I can confirm the NAT rule works as well, as loading up 7 days I can put in the PF Sense IP and it does connect.

I have a second server that hosts NWNEE and that one posts just fine (yeah, different but it works) whereas 7 Days just won't.

I don't quite know what's going on, everything seems right, but it's just not playing ball. Anyone have any ideas that might work?

Need more ports open. 26900-26903 for sure, might need to go to 26904. Also 27000-27030 helps for Steam network communication.

Opened up to 29604 but still nothing. I unfortunately can't forward 27000-27030 because two machines (mine, my girlfriend) occasionally host from our machines and it would mess with that.

It worked prior to the ISP change with just up to 29602. Here's the relevant info from the backup config from the old router (ISP supplied):

I've gone to an Archer VR2800 instead of ISP supplied this time as the ISP supplied one was awful. The port forwarding is straight forward in it:
