Mark,
I could not help but read with interest your comments on 3rd party
firmware for the linksys router
I am having a similar problem here and have long suspected the router.
I see packet come in, and I see jnos respond, but no connection is ever
established.
I have tried everything I know how to get the router to leave the jnos
packet pass through
unmolested. In my reading up on the subject, it sounds like there are
certain parts of the linksys
operating system I can not control.
Any insight would be appreciated.
