The problem is (at least on FreeBSD) that there is a bug with bpf and/or GRE. The 0x6002, 3 and 4 packets never get delivered. -brian On Jan 16, 2014, at 17:29, Mark Abene <phiber at phiber.com> wrote: Using the ip_gre kernel module with iptunnel to configure and bring up the GRE tunnel, it would be rudimentary to match on 0x6002, 0x6003, and 0x6004 in the tunnel packets using a netfilter module such as http://www.netfilter.org/documentation/HOWTO/netfilter-extensions-HOWTO-3.h… It's not rocket science. :) On Thu, Jan 16, 2014 at 10:53 AM, Brian Hechinger <wonko at 4amlunch.net> wrote: A GRE tunnel won't do much good if he can't route DECnet packets over it. Is there a reasonable Linux DECnet router? If not, you may want to try out Paul's python one. -brian On Jan 16, 2014, at 13:40, Dave McGuire <mcguire at neurotica.com> wrote: Oh ok. I'm sorry, I misunderstood. I can set up a temporary GRE tunnel with you this afternoon if you like, until we can get you folded into Brian's tunnel configuration management system. Let me know. -Dave On 01/16/2014 11:51 AM, Mark Abene wrote: Sorry if it wasn't clear... Two different threads had a little cross-posting I think. Here I'm just trying to establish a solid HECnet peer. Johnny-bridge would have been preferable since I'm running this on my NAS (and I know 'bridge' works), but if a GRE peer is easier to find, by all means. While my QNAP NAS does have several tunneling options in its stock config (it's linux arm), it appears they did not include the ip_gre module, so I'll have to see about hacking that in. Assuming that goes well, who's solidly offering the GRE tunnel? We can exchange IP's and configs off-list.

If you want a full-on HECnet connection via GRE, Brian Hechinger can stick your info in his database, and tunnel configurations will be automatically generated for all of us on his next run. -Dave On 01/16/2014 02:12 AM, Mark Abene wrote: Seems rather counter to the idea of HECnet if it's this difficult to join it.
