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?
