You would need to configure all devices on your LAN on a single subnet in order for port forwarding to work correctly.
- I have 20 devices, I would assume all are on the same subnet - they are all on Default Group - and all within the x.x.1.yyy - yyy range
Upon further investigation, it appears that you have the modem configured in 2 different LAN subnets.
Let us know how it goes.
Just migrated from TPG ADSL2 to NBN HFC and it is not smooth...
I have the TPG VR1600v router and I can't get basic port forwarding working either. I tried a lot of different things. I had this working fine with TPG ADSL and my own router before...
Did you finally get it to work?
I can only pinpoint this to an issue with the router... But I can't find firmware updates, it seems that TPG may have to update them on request (is that real?).
Note because this seemed to cause some discussions that I have (unfortunately) inherited a WAN Dynamic IP address. Another big disapointment of the migration... But this should have no impact on port forwarding anyway (I forward to a static IP on my LAN).
See Screenshot below - to allow kids play network game with server hosted locally (on IP address 172.16.1.18) - Starbound server uses TCP port 21025.
Make sure the internal IP is correct - below is 172.16.1.18.
This means any packet that is destined from internet that hits the Internet (WAN) IP address on TCP port 21025 will be pass through the local are network as destination 172.16.1.18 on TCP port 21025.
hope this helps
Thanks for the help!
I actually kept looking for issues in my conf and found that I changed the gateway IP that was new with the new router but forgot to restart the interface! All good now, problem was on my side.
