VPN blocking DCOM? What?

Archived from groups: comp.dcom.vpn (More info?)

I'm looking into using a software package that relies on many DCOM objects.
When I asked the Software vendor if we could use the software over the VPN
link they said:

According to the Wonderware SR # 2461129

VPN is not supported across a Galaxy. It blocks DCOM which will
disable many
things such as Platform Manager and Object Viewer. Authentication
with a domain
will not be updated throughout a galaxy, you will have to
authenticate on the GR ->
Domain Controller each time you log in at a new site. InSQL will not
work either.
The only way it will work is to have a dedicated connection to all
the machines.
Not through the Internet. In order to get AppServer and InSQL to
work they will need
at least 1Mb/s bandwidth. So, they will need to call their phone
company and set up
a leased line that will directly route each site to the GR with that
bandwidth.

Which does not make sense to me as my Cisco PIX to IOS FW router does not
block any ports. I have Domain Controllers on the other sides of DSL
Connections and they Sync up just fine with the Corporate Servers.

Any Ideas on why they might be saying this?



Thanks,

Scott<-
