inside source static route brought down the router?
|
|
| looker 2003-04-26, 7:24 am |
| I just added an inside source static route to a device inside my network. I
added this in remotely through hyperterm, and once the statement went in,
the router locked up. No big deal it is still in testing mode, but curios
why that happened and what can do to prevent it from happening again.
First let me say there were NO devcies on the subnet I routed to, could that
have been the problem? If so how can you configure a router off site and
then bring it live?
Any ideas?
Thanks

You changed a NAT statement or you changed a static route? It's not
clear what you did. But either can cause you to lose your connection.
Your best bet is to telnet in from the next immediate hop router.

| Did you do a true 1-to-1 NAT translation or just map some ports ? This has
happened to me and it was because I NATed my only public IP completely to a
device on the inside network which made the router seem to "lock up".

| As a rule of thumb Always remove NAT from the physical interfaces and then
clear ip nat trans * before making changes to your nat configurations.
after your changes are in then re-apply the nat to the interfaces. I used
to lock up my routers all the time because some translation was already in
the table.
if you do all this in a notepad script before hand the downtime is only like
5 to 15 seconds.
