Hello All,


Isn't it always the way that when you ask for help with something you then manage to find out how to do it yourself.

I now can ping successfully from a machine on green on IPFire1 to a machine on green on IPFire2.

I had been using the FQDN for the local and remote machine names and these were being sent out to the internet for name resolution for some reason. The FQDN's are defined in the physical IPFire that I have . Anyway changing everything to IP's made it work for me.


Regards,

Adolf.
