I need to intercept the communication between a client computer and the server computer, this communication is done via TCP sockets and i have to store that data in a server.
A TCP proxy can be a right solution or what should i do?
Thanks and sorry for my poor English
A tcp proxy can do the job. Also you could use wireshark on the client or server computer to capture the traffic.

so, I have been struggling to figure out how to do port forwarding with a gryphon router
when going to the default gateway link thing it seems not to have an option for anything, including port forwarding, which i expected to exist.

When I do socket programming, I found at least one computer has to have a public IP to make the connection (or reverse connection). I'm wondering if it is possible for 2 computers that are behind different routers to connect to each other (and they don't have port forwarding and don't use proxy)? If that's not possible, how bit torrent works for computers that are behind routers? Does it mean the computers that are behind different routers cannot share among each other?
Bittorent clients are using a protocol named uPNP, that tells router to redirect specified port in bittorrent client to computer that runs client.
Here is more information about protocol.

so I am planning to make a network analyzer using Perl. But before I start I have to answer this question, can a Perl program actually sniff packets in multiple NICs simultaneously? a feature of the program im going to make is that it needs to sniff the packets in the whole LAN within a switch. Is this possible in Perl?
Sniffing packets in the whole lan is not possible. It is only possible if your switch supports it. Many swith has an option to copy all traffic to one of its port for monitoring/sniffing.

When creating a service I see in the list of internal endpoints an entry the looks like myservice.sandbox-cluster:0 TCP along with the ports I explicitly opened. What is the port 0 entry for?
If you are using the GCE Load Balancer, port 0 may be created. port 0 usually means "use any random free port".
Here is the GitHub issue. Here is more info. Email thread about this is here.
