> When a client on the same internal network as the Port Forwarding requests a connection
to the service's public IP address & port , the connection breaks.
> EX : Port Forwarding for TCP Public_IP:1234 to Private_IP:22
> a client(in private network) do => $ssh root@Public_IP -p 1234 => $ ...time out
...
> Solution : In Virtual Router do
> $ sudo iptables -t nat -D POSTROUTING -s Private_CIDR -p tcp --dport 1234(public port)
-d Private_IP -j SNAT -o eth0 --to-source
> $ sudo iptables -t nat -I POSTROUTING -s Private_CIDR -p tcp --dport 22(private port)
-d Private_IP -j SNAT -o eth0 --to-source
> https://github.com/apache/cloudstack/blob/master/patches/systemvm/debian/config/root/firewall.sh
> 74 : (sudo iptables -t nat $op POSTROUTING -s $vrGuestIPNetwork -p $prot --dport ***$port***
-d $guestVmIp -j SNAT -o eth0 --to-source $vrGuestIP &>> $OUTFILE || [ "$op" ==
"-D" ])
> have to change ??  =>
> (sudo iptables -t nat $op POSTROUTING -s $vrGuestIPNetwork -p $prot --dport ***$guestPort***
-d $guestVmIp -j SNAT -o eth0 --to-source $vrGuestIP &>> $OUTFILE || [ "$op" ==
"-D" ])
> Thanks.
