SOHO6 & EdgeX5 Custom Port Problems

[razillian]

I was trying to setup my SOHO6 to route a custom port (31099) over to one of my computers (PVR Box) at home for access across the Internet. The custom port mapping should have been no problem as I have PPTP going to a server already and HTTP going to a different box, etc, etc. But for whatever reason the SOHO6 would not allow traffic on port 31099 to flow through.

After a little investigation I discovered that anything from port 29000 and up will not pass through a SOHO6 (ver 6.3.2). So I swapped it out with an Edge X5 running 7.2.1, and wouldn't you know it, same thing. I upgraded the Edge to 7.5 just to be on the safe side to no avail. Below is the error logged for incoming only:

discard from EXTERNAL_IP_ADDRESS port 48411 to EDGE_IP_ADDRESS port 31099 TCP SYN (default)

If I attempt to connect from inside to the outside address I get the following:

discard from INTERNAL_IP_ADDRESS port 4049 to EDGE_IP_ADDRESS port 31099 TCP SYN (port not available)

If I change the service to use port 28999 or lower, it works, but that is not an option in this case (nor should I have to). So does anyone know how to overcome this problem with either the SOHO or the EDGE? Much appreciated.

is there somewhere where you can turn off Blocking SYN flood attacks ?

No configuration stuff for that, at least not that I can find. The web interface is pretty basic, and I don't know if there is another way to configure these things. I'm a Cisco guy so I have tried telneting to it, to no avail.

there is a WG forum listed in the FAQ that may be helpfull as it is monitor by WG techs and they may know of a workaround

good luck
