[Cerowrt-devel] SIP ATA device trouble over wireless Ethernet bridge [NAT-related?]

["R." <redag2@gmail.com>]

My setup is the following:

Cable modem <- Netgear WNDR3800¹ <- Linksys WRT54GL² <- Linksys
PAP2T-NA (SIP ATA device) <- Phone


While running OpenWRT, the setup was working fine. The ATA was
connecting/registering without a problem. It does NAT-traversal and
has STUN enabled.

While running CeroWRT, the setup has had many hiccups. I read on the
Wiki³ that Cero might have NAT disabled by default.
I tried many different firewall settings to get it working, without
success. I've tried putting everything on "accept", "masquerading"=ON
everywhere, and tried assigning ge00 to all possible (default) zones.

Any ideas as to what could be causing this?


¹ Running  Cerowrt 3.10.40-6
² Running Tomato
³ "CeroWrt is a test platform, and as such we wanted it to co-exist
within existing networks as best as possible, without conflicting with
an existing network, and to not require NAT in order to function
inside that network. NAT skews some test results horribly."
