SRCDS for L4D2 - Problems with DD-WRT router

lippnc · **Author**

I can host a SRCDS fine with the stock firmware on my TP-Link router. When I flash over to the latest DD-WRT, the server will not show in L4D2 or HLSW. I need to use DD-WRT for other things that stock firmware doesn't do. Does anyone know the magic setting or settings I am missing that need to be set in DD-WRT?

I have UPNP disabled. I have Block Anonymous WAN Requests (ping) disabled. I have Filter WAN NAT Redirection disabled. I have tried combos of these enabled and disabled to no avail.

Any assistance would be greatly appreciated. Thanks in advance.

Restore DD-WRT NAT Loopback

iptables -t nat -I POSTROUTING -o br0 -s 192.168.1.0/24 -d 192.168.1.0/24 -j MASQUERAD

Solution: Run above within management > run command > save firewall

I tried it and
"iptables v1.3.7: Couldn't find target `MASQUERAD'"

It's spelled MASQUERADE though not sure if that'll fix the entire issue.
