Hello All,
I am running squid as reverse proxy and its working
fine.
Now i need to set iptables rules to forward ftp
ports directly to backend server for file upload.
I set in prerouting rule as
/sbin/iptables -t nat -A PREROUTING -p tcp --dport
20 -d 172.16.1.10 -j DNAT --to 172.16.1.25
/sbin/iptables -t nat -A PREROUTING -p tcp --dport
21 -d 172.16.1.10 -j DNAT --to 172.16.1.25
Note: Reverse proxy and backend servers are running in same network.and by
reverse proxy has only one network interface.
but i was not able to connect to backend server.
In tcpdump i can see a request from client to squid server but it is not
forwarding to backend server.
What is the correct rule to forward the ftp ports to backend server.
Regards,
Sathi |
