Fish, you are the guru of the LCS interface.
I am?! When did this happen? Seriously! I know a little bit about LCS, sure, but I would hardly classify myself as a "guru"! (Especially not for Linux!!)


Hope you see this post.
You may have some insight for troubleshooting this.

You are on the right track.
I am?! How can that be?! I never responded to Patrik's post!

And the reason I didn't respond was because whatever his problem is completely out of my league. I know virtually NOTHING about Linux networking. (His use of "IUTSAMEH" in his guest's TCPIP profile is also something I'm unfamiliar with.)


Can you look at any stats that show dropped packets? This might
tell you how far the response got before it could not make it to
the host.
You must be talking to Patrik and not me! Yes?


Also, it is a little unclear which component you are wanting to
respond with the ARP? OMVS or the host based bridge.

Can you get the bridge to do a packet trace? Or the TCP/IP trace
at the Layer-2 level? This might be informative about who is
responding (or not).
A packet trace would probably help. I use Wireshark myself on Windows. I have no idea what you would use on Linux.

Sorry I can't offer more, but as I said, Linux networking issues are *completely* out of my league!

Sorry! :(
