Checkpoint Gurus:

When I configure DLSW communication, it can't use NAT
and it requires one of external IP address defined as
internal IP address in order to establish DLSW peer.
i.e. External DLSW router is 1.2.3.1/255.255.255.224,
and I need to set 1.2.3.50/255.255.255.224 as the
internal peer. Even though I differentiate them by
different subnets by defining 1.2.3.0/27 as external
and 1.2.3.32/27 as internal, I still received Address
spoofing in firewall logs. The internal NIC of the
firewall alert this. I did multiple pings and run
tcpdump, I did see packets coming in and out with ICMP
echo/reply as usual, but I don't the reply from the
router. Please advise....
