Help with iptables rules

Hi, I've installed tomato shibby and using it as OpenVPN client. Say for example the tomato got ip 10.9.0.2 as OpenVPN client. Tomato WAN ip is 10.82.4.1 and LAN ip is 192.168.5.1.
Sometimes I also connect directly to my OpenVPN server using my laptop and got ip 10.9.0.3. The problem is, I'm unable to enter tomato admin page using OpenVPN client ip 10.9.0.2. I believe it is firewall routing configuration.
Can you please show me the iptables rules (nat?) so tomato admin page accessible from...
