Does the host have the correct default gateway (172.27.3.10)?

also, can you post "sh ip route" from the 1900 router?

Dear Raza,

yes i can ping 172.27.3.10, and i put it as a gateway of the PC

this is the show ip route:

Gateway of last resort is 172.29.18.125 to network 0.0.0.0

S* 0.0.0.0/0 [1/0] via 172.29.18.125

10.0.0.0/32 is subnetted, 1 subnets

S 10.205.20.50 [1/0] via 172.29.18.125

172.16.0.0/24 is subnetted, 4 subnets

S 172.16.1.0 [1/0] via 172.27.3.1

S 172.16.2.0 [1/0] via 172.27.3.1

S 172.16.3.0 [1/0] via 172.27.3.1

S 172.16.4.0 [1/0] via 172.27.3.1

172.27.0.0/16 is variably subnetted, 4 subnets, 3 masks

Hi,

what kind of host is this ? Is this a PC( which OS ?) or is this a router with no ip routing ? in which case have you got the ip default-gateway command configured ?

Also does R2 have a route back to the subnet the PC is in ?

Regards

Alain
