Issue/Introduction

Configuring a chaining of SOCKS proxies
You want to know how to configure a chain of SOCKS proxies

Resolution

To configure a chain of SOCKS proxies you will need to define the upstream proxy as a SOCKS gateway and then forward to it using policy.

CLI command to create a SOCKS gateway......

ProxyA#(config socks-gateways)create DMZSocks 192.168.254.20 1080

CPL (which can be generated by the VPM)

socks_gateway(DMZSocks) socks_gateway.fail_open(no)

This rule sends all traffic to the SOCKS gateway. To be more specific about which particular traffic you would like forwarded to this gateway you will need to define specific source, destination, or service type triggers.

SOCKS client ---> ProxyA (Internal proxy) ---> ProxyB (DMZ proxy) ---> WWW (SOCKS server)

For more information about using the SOCKS gateway, please refer to to the Configuration and Management Guide (CMG) for the version of SGOS that you are running.
