Multi wan gateway routing ? (packet marking ?)
Hello everyone and thank you for your interest and expertise.
I am trying to implement a multi wan gateway routing, multi vpn with PFSENSE.
Vpn are under the Treaty Linksys RV042 router.
The objective is to make backup links
RV042 –------ ===== VPN1 ====== RV042
LAN1 pfSense ------- RV042 -------- ===== VPN2 ====== RV042 -------- pfSense ------ LAN2
RV042 -------- ===== VPN3 ====== RV042
To do this I use the rules by assigning a gateway in the advanced rules (eg from LAN1 to LAN2 port 80 is use gateway VPN1, same but reverse LAN on the other pfsense ...)
Before going under pfSense I used the packet marking with IPTABLES ...
My concern today is that a packet sent from LAN1 to LAN2 via the VPNx hand on the correct link, but when it returns, pfSense does not know who has apparently transmit ...
MY QUESTIONS :
PfSense he is able to help me?
Is what I use the right method?
What I do not understand?
Thak's for your interest.
