Hello list,
I've recently set up a VPN from a� pc behind an ADSL router which is
doing
PAT.
Finally solved problems of NATing with udp-encapsulation.
The PC is a W2K Pro with SR v4.1 3DES Build 4174, let's say it's IP
is
172.16.1.2
The Firewall is a SPARC/Solaris 2.6 with FW1 v4.1
Now the problem is:
1- If I connect to the inet with a single dial-up and start the vpn
with a
public/legal ip on my local interface, everything is working, my
src-addr
gets NATed with an address of the IP-pool. I can see the decrypt
entry
saying 62.81.27.x is translated to 192.168.1.1.
2-If I connect to the inet with ADSL connectivity, and I have a
private addr
on my ethernet, I can see the decrypt entry in the log saying
172.16.1.2
being translated to 192.168.1.2, which is desired. But, in fact,
packets are
not being translated.
I've contacted Checkpoint for this issue and the asked me too add a
so
called "noisy rule" to drop all NBT traffic. This doesn't make for
me, i
need netbios. It didn't worked indeed.
So, anyone out there knows what's happening?
a undocumented bug?
any idea?
thanks.
