Hi,

Please forgive the noobness;
I'm trying to set up a router and i don't know how to do what I want to do Smile

I have 1 device on the network that I would want to route via a proxy.

For example, Laptop1 should always use this proxy x.x.x.x when going outside the network.

The reason is that I have a Polycom hard phone that has to have a US IP, prior to attempt connecting to SIP.
Also, I would want to do the same with my Amazon Firestick. (All FireTV should go via the noted proxy)

I will set these devices with a fixed IP, not DHCP

How can I do that?

Unfortunately very little information, no router, no build, nothing about the proxy server but in general you need a PREROUTING rule and a POSTROUTING rule see:

My apologies, Tp Link Archer C7 V2; Firmware: DD-WRT v3.0-r40559
I know nothing about the proxy server except the fact that I use it with SwitchyOmega for specific websites.

Your build is old and horribly outdated with known security vulnerabilities.

Latest build is 50176

See: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

*After* update reset to defaults and put settings in manually never restore from a backup (to a different build)

If I have time I will see what SwitchyOmega is but at the moment I am busy with other projects
