Berry, Do the routing tables on the 3 linux instances look identical? Can you see all the vswitches register all the IPs? Usually when we have a problem like this its ACL's.

Two of them, TEC and TGW, have a fully functional network connection. But the third, the TMR, can't connect to the outside world. This is the case since last Friday, after a reboot of the guest. The guests run on zVM 5.4 RSU 802. The guests are connected to two VSWITCHes. One is the production network and the second is a dedicated network for TSM backup purposes. Accessing the TMR can not be done from outside the network. But we can logon to the TEC and then connect to the TMR from there. So I'd expect the connection within VM (vswitch and such) is correct. Now we are puzzeled as to how to proceed. We have been working with several groups (network, linux, VM etc) to get to the root of this problem but with no success so far. The network configs in all 3 guests are the same, other than the obvious IP addresses. We did see that a ping had been travelling through the backup network but disabling this network didn't make the production network available. Restarting the network, detach/define of the NIC etc didn't help either. Do you have any suggestions what we can do next?
