I have a 2851 that I am trying to configure for incoming nat (from
Internet to the inside).  I copied the configs from another router (not
2851) that is working fine.  The only difference is that the inside
interface is now on a VLAN. 

An extract of the config is below:

Any ideas welcome


---------------

interface GigabitEthernet0/0
 description Internet
 ip address 66.zz.zz.zz 255.255.255.240
 ip nat outside
 ip virtual-reassembly
 duplex auto
 speed auto
!
interface GigabitEthernet0/1
 no ip address
 ip nat inside
 ip virtual-reassembly
 duplex auto
 speed auto
!

interface GigabitEthernet0/1.50
 encapsulation dot1Q 50
 ip address 172.21.xx.xx 255.255.255.0
 ip nat inside
 ip virtual-reassembly
 no snmp trap link-status

 

ip nat inside source static tcp 172.21.xx.xx 22 62.zz.zz.zz 3673 extendable
ip nat inside source static tcp 172.21.yy.yy 22 62.zz.zz.zz 3674 extendable
