problem with LAN connection enet udp

[grump]

Connecting from one machine on the LAN to another machine on the same LAN through the router's public IP address using static NAT/"port forwarding" requires explicit support from the router. Not every device can do it.

It's called hairpinning.

@togFox can you show a snapshot of your router configuration?

I'll do that in a few days - after vacation. Thanks!

Establishing a server with sock.lua

Code: Select all

server = Sock.newServer("*", 22122)

Establishing a client:

Code: Select all

client = Sock.newClient(GAME_SETTINGS.hostIP, tonumber(GAME_SETTINGS.hostPort))

if on same computer or on lan then GAME_SETTINGS.hostIP = 192.168.20.4

if on internet/WAN then GAME_SETTINGS.hostIP = whatever 'whatsmyip' says.

GAME_SETTINGS.hostPort = 22122

Edit: to reiterate, sock on same machine and LAN works. Internet does not work. Sock doesn't throw an error so idk. It looks like the client searches and times out.

Let me know if this is not the right screen.


Thanks.

Looking at it your NAT looks fine as it should accept 22122 and then redirect to 192.168.20.4:22122 (Make sure that is your server's private ip; as some routers usually refresh/cycle ip addresses every 24 hours or so unless you've assigned it to it's mac address)

If firewall allows LAN within the private network then, it should allow WAN - so it wouldn't be an issue there. So just double check your server's private ip for the NAT. It's the only thing I can think of looking at it
