sonicwall pro 3060 / di-604

Archived from groups: comp.security.firewalls (More info?)

Hello,
At my office I have a sonicwall 3060 with vpn. At home I have sonicwalls
client thing, to enable me to log in. All works fine. I've got a few PCs
that I want to share the net with at home, so I've gone and purchased a
d-link DI-604 which works fine, except I can't get the VPN passthrough to
work... That is, phase 1 and phase 2 both work fine, and according to the
snwl connection monitor, I have a vpn tunnel established, but I can't ping
anything on the office side. According to the traffic monitor, I'm sending
encrypted data, but I'm never receiving any back.

Not sure if it helps but:
phase 1: preshared, des, md5 and DH2
2: esp with des and md5

vpn pass through is enabled on the dlink, and port 500 tcp/udp are set to
fwd to my local lan ip. Anyone think of anywhere I'm going wrong? Also, my
local ip is in the range of 192.168.0.0/24. Now, somewhere at work, the
192.168.0.0/16 IP addresses are used for remote sites (actaully some of our
stores). Does this matter? I'm assuming the sonicwall at work just goes of
the public address my ISP has assigned me (or my router). The actaul address
of 192.168.0.1 of my router isn't actaully used at work... But it's probably
subnetted off to somewhere else...

Hope taht all makes sense, any help appreciated!

Cheers
Barry

I've tried sticking my ip in the dmz... makes no difference that i can tell.
I dont understand how the tunnel is created yet no data ever returns to me
from the other end...

hm no option for that. Is that the protocol thats used after the tunnel is
created? As its created fine.

wtf does vpn passthrough actaully do....?
