AT&T U-verse VDSL "fiber to the node" 24Mbit down / 3Mbit up
2Wire Router Model 3800HGV-B
Software Version 6.1.9.24-enh.tm

The 2Wire router appears to have a limit of 1024 TCP and UDP sessions. This limit appears to apply to all sessions regardless of any static IP, firewall off, DMZ plus, secondary router configurations.

I've tried using the 2Wire router alone and also configuring the 2Wire static IP addressing, firewall off, DMZ plus, etc. setup along with my own pfSense router/firewall. Either way it appears I exceed the 1024 session limit and sessions start being reset.

Running out of sessions isn't being caused by torrents or p2p etc. We're a business and our legitimate uses are exceeding this session limit.

AT&T tells me it's not possible to bridge the router or increase or avoid the session table limit.

I'm curious if anyone has found a way around either of these issues.
