Hi,
When , we configure pppoe client, there is option to assign the interface wan port
I want to configure pptp or l2tp client, How can I assign the wan internet of that?
For example, I have 2 ISPs isp1(Ether1) & isp2(ether2). So i want to configure pptp or l2tp client that should pass through isp2.
Separate gateway for 2 VPN clients.

VPN-1 Gateway to ISP-1
VPN-2 Gateway to ISP-2

If anyone have idea, please guide

Assigning or forcing vpn out a specific WAN interface, is totally different than assigning the ISP connection to an ethernet port or VLAN.
