BGW210 Port forwarding: Dropping most packets to specified port
I have a couple of computers on my network that need specific ports forwarded to them. This is usually no big deal and the BGW210 interface is quite user friendly. I am however experiencing quite a bit of packet loss only with traffic aimed at the specific forwarded ports... the rest of the internet is running smoothly. I've been experimenting all weekend and have it whittled down to a very simple setup: one desktop with ethernet connected to the BGW router. Once configured:
1) I can see the open port on CanYouSeeMe.org! 🙂
2) From any computer on my LAN, and specifically from the computer with the open port I can psping the computer:port and get consistent responses 🙂
3) While attempting to psping my external IP from the computer that has the open port I get timeouts very consistently on 2 out of 3 accesses. 😞 (the first access very consistently always works)
There is nothing in the router firewall/system logs for the time period of the above
One more data point: Before I realized something was broken, I had a device outside my network periodically phoning home by pushing a bit of data inward and I noticed that only about half of the records actually made it.
Non preferred aside: Setting my computer to Default Server did not improve things (I also tried un-forwarding the port), but IP PassThrough did. Unfortunately that only works for one address and I need two, so Id very much like to get just basic port forwarding working reliably but I'm not sure what to try next. If anyone has any other thoughts, I would appreciate hearing them.
