Is there a way to set the source address to gateway monitor?

gprada

Hello there!

I have a SG-2100 box with three interfaces. An Internet, a MPLS and LAN connected. The network betwen SG-2100 and MPLS router are not routed to remote office, but LAN network yes. I need to monitor the status of MPLS pinging remote router, but only works if I set the source address with LAN IP.

Is there a way to set the source address on gateway monitor?

Thanks in advance

Source address translation is done by outbound NAT rules on pfSense.

Switch the outbound NAT into the hybrid mode, save and add a rule:
interface: WAN
protocol: ICMP
source: This firewall
destination: Network, enter the remote routers IP and /32 for mask
translation address: interface address

Hi @viragomann
Thanks for your reply, but traffic by MPLS are not Nated.

But it could be and by doing that the other side will be able to reply.

Your rule need only apply to the monitoring pings. So you probably want it on the MPLS interface.
