Re: Z/10 - Z/196 Migration SLES9 No Connectivity
Changed the route statement and things are looking better. Initially the z/VM IP address was set as the route gw (carry over from the z/10); that wasn't working so I changed GW to the address of the actual router on our subnet... (Could swear that I tried that already). Now the guest is pingable and the guest can ping outside the subnet. I'll post any additional issues that I encounter. Appreciate the replies so far. Thanks.

Re: Z/10 - Z/196 Migration SLES9 No Connectivity
Can the gateway access the other subnets? Is there a firewall on the other side of that gateway that might be stopping you?
