Hi all, I faced some strange behavior of autoyast when performing installation throught a firewall... the machine I want to install with autoyast is in a dmz. => firewall between this machine and the depot. After the boot, I use the usual command line kernel linux autoyast=nfs:// ... install=nfs:// ... hostip=.. netmask=.. gateway=.. this line is correct and works with other machines not in the DMZ. I reach the step "searching for info file......" but. the system always gives me the message "source not found" and brings me to the manual mode. Then I reconfigure the network manually. The only detail that change with what I typed in the command line is the gateway (nothing in the filed) And now.. no problem... loading ramdisk ... Second strange things: while retrieving the control file... the system does not match his IP with the name of the file. thus I have to type the name of the file manually (its name is the IP address converted in hex) => What are the port I must open on my firewall so that everything is find? kind regards, Damien.
