UPS Worldship connection problems with new firewall device

[Servie Platon <servie_tech () yahoo com>]

Hello FW-Wizards and gurus,

I have upgraded my Sonicwall SOHO3 to TZ170 a couple
of weeks back for my small office network.

Everything seems to be working fine except for one
laptop which accesses UPS (United Parcel Service)
Worldship network.

As its description from the UPS website. UPS
WorldShip® is a full featured, Windows®-based,
shipping software application for customers with high
volume shipping needs. WorldShip allows customers to
accelerate, streamline and enhance not only their
shipping processes, but financial and customer service
processes as well.

When we first installed the program in one of the
laptops, it seems to be working fine with the SOHO3
firewall.

And when, we upgraded to the Sonicwall TZ170, that's
when the problem started to set in. We were told by
UPS technical support since we have upgraded a
firewall appliance, the firewall rules may have
blocked inbound and outbound communication between our
small office network and UPS's network.

Furthermore, we were told that we need to enable
support for gethostip.exe, shipups.exe, upslnkmg.exe
alongside allowing access for 153.2.x.x network.

Since I don't see any documentation on this Sonicwall
TZ170 to do the adding of .exe files to the firewall
that supports this method.

I am uncertain though, whether my firewall rules have
something to do with it? AFAIK, other services such as
mail, terminal services are working fine except for
this one.

One odd thing that puzzles me is that if my boss
brings this laptop to his house and connect it to his
Home network through his router, he could connect to
UPS and be able to do work and send info in a
bi-directional manner.

Whereas, if he returns to the office he gets an Error
Code 53670 which according UPS has something to do
with our firewall and dns resolution.

I have attempted and failed to enable this feature and
am hoping that maybe someone may have encountered this
problem in the past who may have the solution.

Again, thank you very much.

Very sincerely yours,
Servie
