Metric is it possible ?

[nomades]

How can I do metric in pfSense?
route -n add 172.18.0.0 192.168.100.1 1 does not work
route -n add 172.18.0.0 192.168.100.2 2 does not work

or web server, is it possible?

network: 172.18.0.0
gateway's: 192.168.100.1 and 192.168.100.2

Thanks

If you are trying to do failover: Look at the loadbalancer/failover functionality.

I have three interfaces:
WAN - Internet
LAN - Local Area Network
OPT1 - MPLS
Tun0 - openvpn

I have two gateways to the network out to the other side.
OPT1 and tun0.

How do I failover to the tun0?

[GruensFroeschli]

First disable automatic rule generation for vpn (under advanced)
then assign the tun as opt interface.
Then follow http://doc.pfsense.org/index.php/MultiWanVersion1.2

FreeBSD doesn't support routing metrics in that way, it would be nice if it did.

You might also want to look into running a dynamic routing protocol like OSPF to exchange routes. That does support metrics.
