Creating local point of access from external site

RouterOS General
1

I was searching for a better subject without success… sorry!

I need to configure a Mikrotik router with an USB 4G modem connected that work as a single IP in a remote network, connect via VPN to another mikrotik (inside our office) and let us connect to remote site network from our office.

Basically I need this:

External remote network 10.14.130.xxx/24
Mikrotik address 10.14.130.240

Office Mikrotik VPN network 172.16.10.xxx/24
Office Mikrotik local network 192.168.1.xxx/24

External Mikrotik with 4G modem must NAT all our traffic from office because remote network gateway is not the Mikrotik.

Is it possible?

Yes it is… Did you have some difficulty in configuring this network ?

No, i’m only researching information before arrival of mikrotik.
The router will not be the default gateway of network but every request coming from the VPN must be natted as the local mikrotik IP.

Sure, you just add srcnat/masquerade rule on internal interface. Then any connection from vpn to local network will have router’s local address as source.
