No, all I saw was the requests coming in on eth2 but no responses.  I 
only saw the requests on eth2 and no other interface on the router in DC-B.

I managed to upgrade it to 3.4.8 but hit problems due to the version of 
iptables being too old.  I hit further problems trying to get iptables 
upgraded and managed to totally mess up Linux on that machine.  It was 
quite an old build of Gentoo that hadn't been updated in a while so I'm 
not surprised with the problems I had with it.

I have managed to get round the problem in the mean time by tunnelling 
all traffic that arrives on the VPN device in DC-B to the VPN device in 
DC-A over the private link between the two data centres.  This 
effectively means that the client traffic always arrives on eth4 in DC-A 
so I don't need to worry about tracking it from 2 difference sources.  
If I have a major outage in DC-A, I can just amend the routing on the 
router in DC-B to route all client bound traffic via eth4 on DC-B.

Once I get the my test Gentoo Linux machine back up and running again 
(it may be a while), I will do some further testing on the later version 
of Shorewall to see if I can get the tracking working.

Thank-you for you help.

regards,
Aidan
