Cisco 850 router

[vsurinovich]

I cannot access next hop on my network from vlan1. For example when I'm trying to ping a gateway from a computer behind the router I'm receiving message "request timed out". I can ping any address from FA4, but not from vlan1 interface.

vlan1 address 192.168.2.1/24

FA4 address 172.27.35.3/24

Gateway address 172.27.35.1

Also,  I'm attaching router configuration.

please advise,

Thank you,

Vladimir Surinovich.

Vladimir,

Is VLAN 1 in up and up mode?

Is there a physical interface added to vlan 1?

Hi,

interface FastEthernet4
 ip address 172.27.35.3 255.255.255.0
 ip nat inside     ----------------->  it should be ip nat outside  this is surely the problem if the gateway has got no route back to 192.168.2.0
 ip virtual-reassembly
 duplex auto
 speed auto
!
interface Vlan1
 description $ETH-SW-LAUNCH$$INTF-INFO-HWIC 4ESW$
 ip address 192.168.2.1 255.255.255.0
 ip nat inside
 ip virtual-reassembly
 ip tcp adjust-mss 1452
!
ip classless
ip route 0.0.0.0 0.0.0.0 172.27.35.1
ip route 0.0.0.0 0.0.0.0 FastEthernet4   ------> get rid of this one 

Regards.
