This rule confuses me.  It seems to say that any connection going 
through this router, if addressed to port 22 or 80, regardless of the 
destination IP address, should be redirected to 192.168.1.3.  If I read 
that right, then your internal network can't reach any web site or SSH 
server except 192.168.1.3.
