Dear NG,
we are working with a tunnel on 2 astaro 6.300.
Everything is blocked. Only the ports which are neccesary are allowed to be transfered through the tunnel.
Unfortunately i need to export the nis (yellow pages) to another machine (which is on the other side of the tunnel). This will normally done with rpc (Port 111). As far as I know - the rpc is connecting to the service and it will tell the service on which port the communication will be continued.
At this time a problem occurs. On which port do the rpc send the next communication? This is random. How can i solve the problem in creating a firewall rule? Are there another solution possible?
Best Regards ....
p.s. 4096 Bit for enrypted certificates are too much!
