srcnat rule not working

Sat Feb 13, 2016 12:25 pm

Hi all,

I have moved a device on my network from one VLAN with a /16 subnet onto another with a /30.

It was on (VLAN10) and has moved to (VLAN5)

RouterBOARD 750GL is and respectively.

Device of interest was now

I have a srcnat rule for source out interface ppp client to a public IP
I have created another srcnat for in the same way as the previous but this one is not working - counters are showing no traffic matching that rule.

I have IPSec policy to allow to be reached over tunnel from another RB750. That is working and I can see the device from the remote network.

Logging rule shows ICMP traffic from trying to reach from its private IP which obviously isn't going to work.

Cannot see any rules higher in the filter or NAT chains that would be causing an issue here.

Any suggestions?
RouterBOARD RB750 - Xilo ADSL2+ (Annex M)
RouterBOARD RB750GL - Xilo FTTC (VDSL)
