VPN to VPN port forwarding

[tehhellhound 8]

I am having an issue. All is well connecting to your VPN service with my R8000 with Tomato and routing clients. I tested your port forwarding by making my router admin interface remotely accessible and it works great with this firewall script

iptables -I FORWARD -i tun11 -p tcp -d 192.168.1.1 --dport 443 -j ACCEPT

iptables -t nat -I PREROUTING -i tun11 -p tcp --dport 443 -j DNAT --to-destination 192.168.1.1

So now I try to setup a VPN on router to access resources on my local network. The VPN runs and I use the same formula with a second port forward, but my packets never reach the server

iptables -I FORWARD -i tun11 -p tcp -d 192.168.1.1 --dport 8008 -j ACCEPT

iptables -t nat -I PREROUTING -i tun11 -p tcp --dport 8008 -j DNAT --to-destination 192.168.1.1

 

Anything I can do to make this work?
