I have a B580 (LAN 192.168.1.115) in the office connected via public IP and pepvpn with a remote B20 (LAN 192.168.204.1).
On wan 2 of B20 there is a teltonika cellular modem (LAN 192.168.199.2).
Locally from B20 lan I can reach and configure the teltonica modem on 192.168.199.2, but not from B580 lan in the office.
I ask if there is some configuration to reach the teltonika modem from the office lan(192.168.1.X).
On the B20 create an outbound policy for 192.168.199.2 set to enforced and use the vpn connection as the route.
Thanks Martin but the rule is created on the B580 (office side). When from subnet 192.168.200.0/24 I call 192.168.199.1 (remote teltonika) the packet is sent trough the pepvpn to the gateway 192.168.204.1 that know his address and then I able to reach it .
Thanks a lot for your assistance.
