We ran into almost exactly the same situation a few weeks ago.  The
difference was that we were using another port on the WAN and redirecting
this port to the 3000.  If we used the standard FTP port, there was no
problem.

However, since FTP worked fine when coming through a VPN, that was good
enough for us.

Subject: [HP3000-L] Connecting Two Lans To The 3000

We have a LAN that uses 10.251.46.nnn with a subnet
mask of .192 (which gives us 64 addresses) and we have
run out of space.  I am locked into this addressing
scheme as it works with our frame relay circuits to
the remote plants.  So, being in need of more IP
addresses, I thought "Why not set up another LAN using
192.168.3.nnn and then connect the new LAN to the 3000
just like my VPN's do?"

Well, easier said than done.

Using a router to translate from the 192.168.3 network
to the 10.251.46 network I can get PC's to connect to
the 3000 using NS/VT or telnet; however, I can't get
FTP to work between the PC and the 3000.  I configured
the router with a LAN address of 192.168.3.1 and a WAN
address of 10.251.46.nnn, and I also configured the
neighbor gateway on the 3000.  Upon investigation, I
found that the reason FTP won't work is because the
router is only presenting the WAN address to the 3000
and not the 192.168.3 address of the PC.  Now on the
VPN's the 192.168 address comes through the router to
the 3000 so FTP works perfectly fine.  This is a
Linksys BEFSR41 router.

Now, I know I can't be the first person who needed to
connect two disparate LAN's to the 3000.  Does anyone
have any ideas on how to make this work?
