[Solved] utorrent server behind two pfsense boxes

[frenzy_usa]

The problem was not in the firewall settings. I did not need to add any firewall rules to pfsense_1. I added some more torrents and they started downloading/uploading in less than a minute. The torrents I originally tried apparently don't have any seeders available.

Placed a second pfsense box between the ISP's modem and my utorrent server and I'm unable to get the nat/firewall/routing correct so the torrent server can upload and download.

Network layout

ISP modem              --> pfsense_1             --> unmanaged_switch_1 --> pfsense_2 --> unmanaged_switch_2 --> utorrent_server
WAN: DHCP                  WAN: 192.168.254.253                             WAN: DHCP                            IP: DHCP
LAN: 192.168.254.254       LAN: 192.168.1.0/24                              LAN: 192.168.17.0/24

The torrent server works correctly when connected to unmanaged_switch_1 and completely fails when connected to unmanaged_switch_2

I use UPnP on pfsense_2 to open and close the torrent server ports.

Have not made any changes to the ISP modems firewall, routing table, or nat rules.

I did set pfsense_2 to routing only via System –> Advanced --> Firewall & NAT but that prevented all computers behind pfsense_2 from even pinging pfsense_1. Adding a routing rule probably would have solved this but I haven't tried yet.

I'd prefer to keep the firewall on pfsense_2 enabled as this the firewall for a raspberry pi cluster that I will eventually be moving from place to place to demonstrate the capabilities of the raspberry pi's.

I tried adding an NAT port forward rule on pfsense_1 and letting the NAT rule automatically manage the rule under firewall->wan but the torrent server still could not upload or download the torrents.

NAT rule on pfsense_1:
Interface: WAN
Protocol: TCP/UDP
Source address: any
Source port: any/any
Destination address: WAN address
Destination port: 45526
Redirect target IP: pfsense_2 WAN IP
Redirect target port: 45526
All other options left at default settings

What should I be looking for in the log files that will help me identify the problem?
