Yes - they're both leased servers, but on different networks, perhaps
different datacenters etc.

That is 88.198.7.133.

I believe so - on the RS, I've got
net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2
> o There's no rp_filter enabled on the RS?
# cat /proc/sys/net/ipv4/conf/all/rp_filter
1
I had to go and read up on that setting - I'm getting a feeling it
should perhaps be 0, not 1? Looks like my SUSE 10.1 sets it by
default.

At least for one server - the datacenter is remote, and more or less a
blackbox to me.

There is, but I've also tried telnet'ing directly from the NAT-gateway.

Well, if you help me sort this one out, beers are on me and you get to
enjoy the beautiful view of the pumpkin field just opposite :-)
