I am trying to use dual isp's connections on CISCO 881 by using static route track. I have problem that I can't ping, telnet secondary router IP from WAN. this is the reason that secondary connection is not doing fail over. sla all commands are ok and its working fine. Its look like issue with nating. only primary route is active and I can ping and telnet from WAN. I want a solution that both addresses are pingable, telnet from WAN, with failover.
