The benefit of the hAP ac² is CPU power. In the end it all depends on your requirements.

See this post for example setup, where a Router is used to connect to various Wifi network, then it uses NAT to and sends wifi out again on a different SSID.
This could be used to connect to VPN as well.
Any Wifi MT Router could do this. Chose your router from need of 2GHz, 5GHz, etc.

In the blog link posted above, the writer has used 2.4 GHz interface to connect to hotel, and 5GHz to its client.
You can as in my link above see example where 2.4GHz are used for both hotel and local clients with different SSID.

I am doing the same like you.
I have two, and it depends of my luggage allowance and the destination (poor wireless there (coverage) or other things)
I have an old 751 and a new mini AP (very small).

hi any body can suggest me about router which can be capable for 2000 ovpn traffic with 4 Mbps bandwidth per vpn

I don't think a "travel router" is capable of doing 2k OVPN tunnels with 4Mbps each (that's 8Gbps of traffic). Ask in different thread.
