Some servers unreachable through VPN

I've had an IPSec tunnel running with pfSense 2.0 for almost a year. Recently, we migrated one of our firewalls and updated to 2.1.2.
After the change, I'm experiencing something really weird: some servers are not reachable through the VPN, while others are perfectly reachable.
My subnets are 192.168.0.0/24 on one site and 192.168.10.0/24 on the other. From 192.168.10.184 (a workstation) I can ping 192.168.0.25 without problems, but can't ping 192.168.0.26.
Both .25 and .26 are Linux virtual machines running on the same physical server. Also, from within 192.168.0.26 I can't ping any of the 192.168.10.0 hosts either.
I checked MTU values, and basic stuff like that, and everything appears to be correct (at least it's the same on a working and non-working server). Can anyone give me a hint?

Have you checked that there isn't a local firewall on '.0.26' that you have magically forgotten about. (I don't know how many times that has happened to me).

First guess, wrong subnet mask on the affected hosts (/16 instead of /24, so it thinks the remote network is local).
