Title: Dir-655 support of UDP hole punching out of the box
Post by: roywax on April 22, 2009, 07:43:53 AM
Hello,

Most routers today support udp hole punching out of the box.

I used di-524 before and it worked fine.

UDP packets sent from inside my private network to a public server were returned to the public address and were let through by the router to the private address sender.

I just bought DIR-655 and this stopped working.
I read that dir-655 firmware has a bug which prevents this udp "connections" from working.

Is that true?

Thanks

Roy

Never heard of that bug. What specific UDP packets are we talking about here?

You might want to play with the router firewall settings a bit, my UDP packets flow the way I want them to.

EddieZ you internal switch Gig Switch in the router is completely different than A3 and A4 which uses Realtek Gig Switch.  Again UDP packets shouldn't have issues. I have my TCP ports and UDP ports working smooth in ports forwarding..

It's the same firmware, the hardware does not have anything to do with it IMHO. It's a purely a firewall setting issue. (see: http://en.wikipedia.org/wiki/UDP_hole_punching)

Try different UDP end point filtering
