Hello,
I'm having a problem regarding a router with a 2 wan link cards
configured both to send and receive traffic at same time, one link to
the VPN, all the Nats (1 to 1 Nat) and internet general traffic and the
other one to receive and send the video conference traffic. I have the
configuration based in policy based routing and I think every thing is
well configured , but the problem is that when I try to ping some public
IP some packets are lost 1 in 4, what brings some delay and packet lost
problems to the communications.
Any one knows this problem or have some clue on whats happening?
Appreciate any help to this matter.
I post here my configuration:
