We have two data centers, one is in New York and the second is in Chicago. Our vendor in the Chicago Data Center is ceasing the ISP Services. We have a circuit between both data center. We have deployed squid proxy on a Ubuntu 16.04 Server in the New York Data Center and are planning forward the internet traffic from the servers in the Chicago Data Center using the Squid Proxy.
We are able to forward the standard internet port i.e 80, 443, but we are unable to forward non standard internet ports e.g. 11002, 55005 that we might use for other data services.
When I run a sniffer from our main office firewall to check the incoming traffic coming from the Chicago data center via 11002 and its is coming via the Chicago ISP instead of the New York Squid Proxy Server.
Any help will be appreciated
