I would like to use a 3G modem connection as outbound automatic failover connection (ADSL is configured as primary wan), but I am not able to make it working.
I configured the 3G modem (Huawei E180) in Interfaces-PPPs, then I added a "3G" gateway in System-Routing-Gateways and I created a "GW_Failover" gateway group in System-Routing-Gateway Groups, adding Wan (Tier1) and 3G (Tier2).
Then I assigned "GW_Failover" to the Lan outbound rule in Firewall-Rules-Lan as explained at http://forum.pfsense.org/index.php/topic,10407.0.html
What I expected:
bringing down the primary Wan (ADSL), the 3G modem should become active (dial up) and the traffic should be routed through the 3G connection. When the primary ADSL connection comes up again, the 3G modem should disconnect and the traffic should be routed through the ADSL connection. I don't need balancing, just failover.
What really happens:
bringing down the primary Wan (ADSL), the 3G modem remains idle and the internet connectivity is lost.
If I succeded (in whatever manner) to make the 3G modem dialing up, all the traffic is router through the 3G connection, and the internet connectivity is restored, but when the primary ADSL connection comes up again, the 3G modem remains connected.
I didn't find any way to bring down 3G connection..... the disconnect button available in Status-Interfaces doesn't work.
I tried also to configure automatic gateway or a fixed one to the 3G interface, but I got the same behaviour.
Here is my configuration:
WAN (default) WAN 192.168.100.1 192.168.100.1 Interface WAN Dynamic Gateway
3G 3G Dynamic 18.104.22.168 Interface 3G Dynamic Gateway
GW_Failover WAN Tier1
ID Proto Source Port Destination Port Gateway Queue Schedule Description
* * * LAN Address 22 * * Anti-Lockout Rule
* LAN net * * * GW_Failover None Allow All (LAN -> Any)
What is going wrong?
