I am setting up NAT on a Linksys WRT54GL for the first time. I'm trying to map a statically-assigned laptop address of 192.168.1.109 to port 40000, and ping it. My end goal is to enable TCP and UDP socket/websocket connections to this machine. It's not working; here are the steps that I've taken. Can anyone spot my error?
On the host laptop:
- Statically assigned IP address of 192.168.1.109
- Set up DNS servers and search domains
Under "Applications and Gaming" in the router
- External Port 40000, Internal Port 40000, protocol UDP, To IP address 192.168.1.109
- External Port 40001, Internal Port 40001, protocol TCP, To IP address 192.168.1.109
(NOTE: aaa.bbb substituted here because I don't want to post my IP address to the world.)
- Default gateway in router is aaa.bbb.82.1
- Router IP address is aaa.bbb.82.134
Results:
- I am able to ping 192.168.1.109 internally, from another laptop.
- I am able to ping aaa.bbb.82.1 (about 90m response time)
- I am NOT able to ping aaa.bbb.82.134
- I am NOT able to ping aaa.bbb.82.134:40000
- I am NOT able to ping aaa.bbb.82.134:40001
Where am I going wrong?
