First you should try to match without SNAT at all with a simple log
target and see if it matches.
I would start with:
iptables -t nat -I POSTROUTING -s 10.0.0.1 -o xbrdg0 -j LOG --log-prefix
"Should-SNAT: " --log-level 4
And then:
iptables -t nat -I POSTROUTING -s 10.0.0.1 -o xbrdg0 -j SNAT --to-source
192.168.100.3
And see what happens.
Also there might be something about this bridge settings and it maybe
needs the "-o eth1" but it would be a bit weird.
