Paul,

I have currently got the same problem on my Maxen (6000s running 
ebixk.m60 6.1.3/6.1.7), I have opened a ticket with EMEA support 
about this. (Ticket #267051)

I've been asked to take a trace of the Ethernet traffic on this 
segment, because the Ascend Tech I'm working with at Sophia TAC 
thinks that the Max is malforming the return ICMP packets.

I find that the WAN side address does eventually age out if there is 
no-one logged on the box, or if there are only dynamically assigned 
users (who don't need a static WAN address on the Max) connected, for 
a period of time.

Here's something I'd like you to try... 

Traceroute the Max ethernet address from a router or machine attached 
to the same ethernet. Do you get the correct ethernet address back? 

I do, tracing from a Cisco 7200 router to a Max on one of it's 
attached Ethernets.

Regards,
Mike
