HTTP Pass-through Policy

[Chaya Pothuraju]

Hello,
I am new to Layer 7 and am trying to set up the API Gateway to proxy transactions between 2 servers. This is to position the gateway as a pass-through layer for all the transactions and SSL authentication between the servers.

Original Flow:
Server_1 => Server_2

Intended Flow:
Server_1 => Layer_7 => Server_2

Currently, between server_1 and server_2, there is mutual authentication that has been configured. Hence, is it possible to introduce Layer_7 API GW in this flow without changing the mutual authentication setup between servers 1 and 2. If so, can someone please point me to any documentation that can help me get started.

Thanks in Advance,
Chaya.

Dear Chaya,
The layer7 gateway will always terminate ssl from front end, and re-establish ssl to the backend.
Therefore you will need to setup mutual ssl between server_1 and gateway, and mutual ssl between gateway and server_2.

Hello Mark,
Thanks for getting back.

From your response, Will the gateway terminate SSL from the calling server, because it cannot be the man-in-the-middle eavesdropper between the servers configured for mutual authentication. If so, can we try to build a policy that will let the gateway function as a HTTPS Proxy, a TCP Proxy or an SSL Passthrough so as to pass traffic between the servers.
Please let me know your thoughts on this.

Thanks,
Chaya.
