Re: SDM1002 on Service Agent connect via VPN

Thanks for the link, Neil. I see that it applies to V5R2, which could help us. I don't have all the PTFs. But I tried port forwarding the ports listed (500 and 4500). The result was, my Remote Desktop from home failed to connect to my XP box behind our router. We are using the LinkSys BEVFS41 (or whatever) that is a 4-port VPN router. I also don't know whether that box will pass the ESP traffic through - it does have IPSec passthrough - got no definitive response from LinkSys, but they are not in the same league as Cisco, of course.

Anyway, I think we'll stick with the phone connection for now.

Vern,

One of these two test systems has a 192.168.x.x address behind a router
running NAT.  The other has a valid public IP address.  No hops though
other systems.  The VPN works fine - it was set up through the IBM
Universal Connection wizard as a Direct connection to Internet - something
you need PTF's for I think - see the end of this article:

Neil, I'm curious - are those systems live on the Internet - i.e., they
have valid Internet addresses? Or do they hop to an iSeries with a valid IP
address? I don't believe the VPN method works if you are behind a NAT-type
router, unless you have an iSeries outside of your protected network.

If the iSeries is a 192.168.x.x type box (or equivalent class A or B), and
you can get out via VPN, I'd love to know how, without a box to hop to. I
wondered (but have not tried) whether it'd work with a DMZ-type setting on
our LinkSys to the iSeries, with port forwarding through the router. Of
course, both those are not anything I'd want to do with a production box.
