<![CDATA[PfSense MultiWan fails every second connection]]>I have successfully deployed several pfSense ALIX and WRAP boards. Now I have a problem getting MultiWan to work. Every second connection doesnt reach its destination. Here's the outline of my network:

WAN
PPPoE
DSL, directly on WAN Interface
|
|
|
LAN
pfSense 192.168.168.0
|
|
|
OPT1
Router IP 192.168.250.1 Subnet 192.168.250.0/24 <– Netgear Router, pfSense as DMZ on IP 192.168.250.2
|
|
|
WAN
PPPoe

What should I set as gateway for firewall rule number one? I've set up everything according to the pfsense multiwan howto for 1.2 and I'm using pfSense 1.22.
No static routes defined. Do I need any because of using PPPoE on the WAN interface?  I couldnt find anything appropiate on the forum. I've even set up a static route for the monitor IP on OPT1, but that doesnt change a thing.
The rule was:
Interface  Network  Gateway  Description 
LAN 212.18.0.5/32 192.168.250.1

Firewall rules:
Proto  Source  Port  Destination  Port  Gateway  Schedule  Description

  • LAN net * WAN address * *   Make sure WAN traffic goes to right interface
  • LAN net * OPT1 net * 192.168.250.1   Make sure OPT1 traffic goes to right interface
  • LAN net * * * LoadBalance   Everything else gets shared out

The system log shows these events periodically:

System log:
Jan 30 14:17:09 kernel: arpresolve: can't allocate route for 192.168.250.1
Jan 30 14:17:09 kernel: arplookup 192.168.250.1 failed: host is not on local network

Furthermore, failover detection doesnt work.
This is my loadbalancer setup:
Name  Type  Servers/Gateways  Port  Monitor  Description

LoadBalance gateway wan 217.237.152.114
(balance) opt1 212.18.0.5 Round Robin load balancing

WAN1FailsToWAN2 gateway opt1 212.18.0.5
(failover) wan 217.237.152.114 WAN 2 preferred when WAN 1 fails

WAN2FailsToWan1 gateway wan 217.237.152.114
(failover) opt1 212.18.0.5 WAN 1 preferred when WAN 2 fails

Even if I disconnect the modem on 192.168.250.0, the link remains UP. Might be because of the system log error?

Any help would be appreciated.
Maybe I'll try to use an additional router on the WAN Interface and switch the WAN interface to static IP. I dont know anything else I could try...

sincerely, localhost
