Re: Hercules with OSA QDIO network connectivity on Windows 11 not working
|
You know Philippe, on a linux host, and an emulated mainframe, they need to be on different networks.?? So you have everything on the same network, 192.168.0.0/24.? Netmask 255.255.255.0 (witch is /24).???
So your 2 network adaptors on the windows host can’t forward from the same network to the same network.? Even though you now have forwarding enabled.? A router can’t route between two network adaptors on the same network.
?
So try this -? leave the windows machine where it is in terms of address and netmask -? change the ZOS machine to let’s just say (and you could pick a different one) 192.168.1.0/24 example 192.168.1.10 mask
255.255.255.0, make you tun0 interface on the windows machine 192.168.1.1/255.255.255.0 – now your home and windows network is 192.168.0.0/24 and your mainframe is on 192.168.1.0/24, you will need to edit the ZOS configuration to the new address.
?
Now you can have a route statement on the windows machine to forward traffic from 192.168.1.0/24 to 192.168.0.0/24 – this puts the ZOS instance on network 2 and your windows machine on network 1 – so that
routing can take place.?? If you don’t understand routing on a IP network this can be confusing and I am not sure how else to explain it.???? But routing will not forward packets from one ethernet adaptor (real or virtual) to another that is on the same network,
forwarding only can happen between two networks, and the network is defined by the netmask.?? So 192.168.0.0/255.255.255.0 is the address range 192.168.0.0 to 192.168.0.254 and everything in that range is on the same network and thus can’t be routed.
?
I hope this helps you, I don’t know how else to explain networking.
?
Thanks,
Dave, N8ZFM

Well you still needed forwarding on for it to transfer packets from one interface to another.?? So yes I see its now on for you, good, you did need that.?? There must obviously be something else you also need.?
I don’t know.?? But you for sure did and do, need forwarding to be on.

Thanks,

unfortunately it made no difference, even after enabling IP routing...
