How to choose a budget router with VPN for a mini office?

Question

VPN

There is a very small office (1 server, 2 PCs). You need to organize the ability to connect to it via vpn for outsourcing support and at the same time place a small accumulation of your resources there (programs for remote channel diagnostics, backups of important data, etc.).
What do you advise? Budget up to about 4.000
I would also like to have cli and acl on it, if possible.
