[HECnet] Getting reconnected

Been awhile since I've posted anything, or been connected but I'd like to work on getting reconnected to HECnet. I would still like to do Cisco connections - just need to pass that through the firewall. Can a more-modern ISR running IOS-XE do DECnet? (specifically a cisco 4321). Worst case I can just re-use the 2851, but that's got a lot of telephony config on it so would like to separate out uses if possible. (Also - you may have previously known me as Cory Smelosky - please update contact details and whatnot) I used to be area 9 - I will continue to use that area. Thanks!
