I think I've misread something, your diagrams say the WRAP board is connected to the DSL line, and the alix board is connected to the cell network, but when you listed your port forwards it seems reversed? Looking at the interface names, the alix board has the DSL and the WRAP board has the cell (labeled WAN).
Do you have failover / load balancing set up between the two boxes? Are your rules to allow all for the lan side of your networks?
If I'm reading it correctly, you're forwarding from the HSDPA-pfsense directly to the client on the DSL-pfsense. Would you not instead port forward to the interface IP, then on the opposite box pick up the incoming and forward to the client?
HSDPA BOX::: Internet (utorrent) > ALIX(OPT1) >port-forward> WAN | DSL BOX::: LAN(WRAP) >port-forward> MacBook Pro?
HSDPA BOX::: Internet (utorrent) > ALIX(OPT1) >port-forward> MacBook Pro, I can only see this working if you create a tunnel between the two PFsenses, but I'm a total newb on it all.
I've setup an ALIX 6E2 with the pfSense-2.0-BETA5-4g-i386-20110203-0154-nanobsd.img. See the attached PNG to understand my topology
I've setup several Port Forwardings on the WRAP and on the ALIX, but can't reach none off the machin's behind that dual PortForward.
Forward on the WRAP:
and on the ALIX:
I hope it's a simple prob and you can help...
