tcpdump shows quite a bit of AT traffic, including:

06:55:54.078248 AT 1.146.72 > 1.105.72:  at-IP 40
06:55:57.126493 AT 1.146.72 > 1.105.72:  at-IP 40

...which should be the MacIP packets.  The issue seems to be with the ability to actually see this traffic in MacGated.  If I set the socket to listen to ETH_P_ALL then it sees plenty that it cannot decode.  I added some debugging to show them but I should spend more time with that.  For the socket I have tried:

//  SockLT = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_LOCALTALK));
//  SockLT = socket(AF_APPLETALK, SOCK_DGRAM, htons(ETH_P_ALL));
//  SockLT = socket(AF_PACKET, SOCK_DGRAM, htons(ETH_P_LOCALTALK));

also htons(ETH_P_ATALK), but only the ETH_P_ALL shows anything so far.  So, only the most critical parts are left to fix ;)
