Correct, as I indicated below, Sorry, I missed that you had already tried extended pings. but this doesn't help regular traffic to get routed though. Why is the other router not in the secondary subnets too? If it's not, then it can't reply unless you have set up routing between the subnets (or a static route). I don't think we really have enough info to help you. Without more info, it sounds like spaghetti. It may be time for a redesign of your addressing and routing (or at least a complete analysis of how it's working now). Good luck with it.

Extended ping will let you set the source address. Type ping and carriage return and you'll see lots of parameters.

Re: Source address issue.
Thats just how it works, its going to use the primary interfaces IP on outgoing ping packets that orignate from the router. Like you said, to overcome that you do an extended ping.
