External firewall setup to enable online updates

I had to enable http communication to secure-www.novell.com. It looks registration script needs to be redirected by the website to https.
Now I’m facing some more common problem: I get this message “Online Repositories do not need to be changed.” while I’m configuring online updates via yast.
System has appeared on my SCC account after I issued this command:
suse_register -a email=myself@my-company.com -a regcode-sles=XXXXXXXXXXX -a addressid=ZZZZZZZ -a moniker=tsm1lz -L suse_register.log
Then I’m runing “Configure on-line updates” in yast. It tells me that on-line repos are not set, and enables me to go through registration again. It is successfull but tells me
“Online Repositories do not need to be changed.”
Now I’ stuck. I have seen these threads:

But the solutions over there didn’t worked for me.
