Found the actual problem!
IPSec VTI VPNs means I can't do source-based NAT/firewall rules to redirect GRE from
the DECnet tunnel IPs to a separate box as is currently configured.
I had to ask the vendor and community for help on this ;)
Dang vyos!

 Hi Cory,
 
 I've updated my tunnel configuration, but I'm not getting any traffic from your
end. I can ping you though.
  
 
 Found part of the problem. ;)
 
 mercedes-sj(config)#ip route 0.0.0.0 0.0.0.0 10.12.0.1
 
 Forgot to add that, along with enabling IP routing and setting DECnet on fa0/0.
 
        rule 30 {
            action accept
            destination {
                address 10.12.0.6
            }
            log disable
            protocol gre
        }
 
 also pretty sure that's not the EdgeOS way to forward GRE...;)
 
  Regards, Tim.
