This is basically a repost of info I sent out to comp.os.vms earlier in the
week. However, I'm not sure it made it out of my ISP since I can't find it
in DejaNews. Anyway I'm basically stuck on getting the DECnet over TCP/IP
working through my firewall. What follows is the info I'd posted to the
newsgroup:
I'm trying to setup a VAX behind a firewall to accept DECnet over TCP/IP
connections. I'm running OpenVMS V7.2, DECnet-Plus, and TCP/IP V5.0. I've
got the following setup:
VAXstation 4000-60 <----> OpenBSD Firewall <----> Internet
AlphaStation 500/333<--+
The Firewall is doing NAT and I've redirected ports 102 and 399 directly to
the VAXstation-60, which from what little documentation I could find on
DECnet over TCP/IP looks to be enough.
I've got DECnet over TCP/IP working just fine between the VAX and the Alpha
(I set it up on the Alpha only for the purpose of testing this). However
when I try and connect to the VAX from the Alpha using the Internet IP
address I can't. This seems to indicate to me that I need to redirect more
than just ports 102 and 399.
The following four lines seem to be the only network traffic when I attempt
a "SET HOST {Internet IP Address}".
15:21:54.144064 alpha.1062 > firewall.399: S
929664000:929664000(0) win 16384 <mss 1460,nop,wscale 0>
15:21:54.144066 firewall.399 > alpha.1062: R 0:0(0) ack
929664001 win 0
15:21:54.146016 alpha.1063 > firewall.399: S
929728000:929728000(0) win 16384 <mss 1460,nop,wscale 0>
15:21:54.146018 firewall.399 > alpha.1063: R 0:0(0) ack
929728001 win 0
Does anyone have any idea what I need to do in order to get this working?
