@Bob As I told before I could not add additional interface .... We have just started development. I am just allowed to follow instruction. And for now I have to configure my IPTables to redirect all ports except one. I would be very thankful if you can help.
@Bob This is not possible with iptables? what I need for now? I am continuously searching about this... I am not expert in iptables but may mangle chain with packet marking could work for me... Just I need a expert to mentor me....
@Psycogeek Other question are about routing traffic to other ip address and some does not match with my scenario. I could mention all those in question if you think it would be useful.
The solution I have removed worked for me but latter I come to know that redirecting port 22 is bad idea. Their are a lot of attack with destination port 22.
