As Alex has said, Masquerading (Or Network Address Translation - to use the 
UNIX/BSD terminology) is required. I do not know where under YAST this works 
- I do not use SuSe. If you are running an 2.2.x kernel, you need to use the 
"ipchains" command. Try:

/sbin/ipchains -A forward -s 192.168.1.0/24 -j MASQ

quite simply, what this does is add an entry to the "forward" chain allowing 
any from from the 192.168.1.0 network to be forwarded. Its Address will also 
be translated ( -j MASQ = "jump to the Masquerade chain")
