Re: I can ping all equipmet however internal router no.

Hello

I think we would have to see some configurations and understand how all of this is connected together (topology).  Does the device you cannot ping have a route back to the device you are pinging from?

Thanks

Have external place call pack with a 1811.

I can ping from corpore office  router external 172.16.10.2 and  I can't  ping his internal router 10.2.1.1 however I can ping 10.2.1.110 computer my internal network in farm. From farm I can ping my internal in coporpore (10.1.1.1 or 10.0.1.1) and all server and computer. Provider is PIN 172.16.10.3.

Again thank for your help.

Re: I can ping all equipmet however internal router no.

Roberto,

I am a bit lost with this.

the 172.16.10.2 address is not on the config you attached, so you must be pinging from another router.

if you cant ping 10.2.1.1 from your 1811. few basics you have to check:

1-on the 1811 do a show ip route 10.2.1.1 what does iit show?  do the same on the next hop

2-do a traceroute to 10.2.1.1 from your 1811 and check your last good hop. log into that and do a sh ip route to 10.2.1.1

please cut and paste your findings in a new post.

Thanks
