I don't think your firewall would distinguish between
"openafs.org" and "employer_domain".
To check the firewall run as root :  "iptables -L".
Or disable the firewall using "Yast2".

Anyway, to see which fileserver of employer_domain is not reachable:
do a
/bin/ls /afs/employer_domain
(fails with connection timedout), then
/usr/bin/fs checkservers

This should give you the hostname of a fileserver failing to respond.

Then you can try to establish a debug connection to that
fileserver via

/usr/sbin/rxdebug  (fileservername) -v

This is the thing you need to get to work first. It can be a firewall
issue on your computers side or on your employers' side.
