I have to connect from my homeoffice to office lan via gre tunnel. my company have put on another public router for incoming connection.
now, my is to configure my 827 for give a second gre tunnel with same ip private destination. All private ip office lan are reach via both public routers.
I try using a gre like this:
in tun0 ip unnum eth0 tunnel source my_public_ip tunnel dest company_public_ip
ip route 192.168.1.0 255.255.255.0 tunn0
also I create a second tunnel gre with second ip route via tunnel1 but it seems not work, loss of 50% packet
in tun1 ip unnum eth0 tunnel source my_public_ip tunnel dest company_second_public_ip
ip route 192.168.1.0 255.255.255.0 tunn1
My answer is: What's the correct configuration for using indistinctly both tunnel ?
