Hi all,
I'm using a CISCO2911 with IOS c2900-universalk9-mz.SPA.154-3.M2.bin.
I have two(2) Internet connections, and I have this issue:
I am forced to use the "permanent" keyword, in my static route, so that the router can forward the packets to the internet.
If I remove the "permanent" keyword, then packets cannot be forwarded. packets cannot be forwarded also if I place the "track" command.
So I had to use the "permanent" keyword for the two(2) static ip route.
Then for test I used the dual ISP example NAT translation.
http://docwiki.cisco.com/wiki/NAT_failover_with_DUAL_ISP_on_a_router_Configuration_Example
If the first interface is down, then the packets are not forwarded to the second link.
The routing table is OK. but packets cannot be translated or forwarded.
If i use the simple ip route with weight then the routing table appears normal if I shutdown one of the internet interfaces.
but packet cannot be translated and forwarded.
Any solutions?
Thank you very much
