Cisco as a proxy server?

Question

Cisco

Dear colleagues!
In connection with the current blocking, the question is whether it is possible to use a Cisco router as a proxy server for external clients, PCs, phones? In the provider's network where the tsiska is used, while access to "forbidden sites" is available. VPN does not like the fact that then all traffic will be wrapped through the router. And you need only one messenger (you can guess which :). I would be grateful to all who responded. Our router is 2851.

No, the server and the router, as you might guess, are different things. On new models, however, you can deploy a virtual machine with Linux and configure a proxy on it, but this is not a good solution at all, and yours will not work either.
However, you can try to play around with the NAT rules, but it's still crooked. You can't do without a separate server, especially since it is trivially configured.
