Remote Telnet Issues

I'm honestly embarassed asking this question but for the life of me I've been unable to resolve the issue. ICMP makes it to ingress but telnet fails from remote subnets. There is another router in front of this device on the same subnet as the ingress, with no ACL's, and this device has no problems with telnet. Anything coming from the internet cannot get a login prompt.

!

interface FastEthernet0/0

ip address x.x.x.37 255.255.255.248

duplex auto

speed auto

!

!

ip classless

ip route 0.0.0.0 0.0.0.0 x.x.x.33

!

line vty 0 4

password cisco

login

!

I've also tried adding "transport input telnet", but that did not correct my problem.

The problem happens even when the config is at it's most basic levels and before I have the LAN segment configured.

Here's the information that you requested though:

!

interface FastEthernet0/0

ip address x.x.x.37 255.255.255.248

ip access-group 100 in

ip nat outside

ip virtual-reassembly

duplex auto

speed auto

!

!

interface Vlan1

no ip address

ip virtual-reassembly

bridge-group 1

bridge-group 1 spanning-disabled

!

interface BVI1

ip address 192.168.2.1 255.255.255.248

ip nat inside

ip virtual-reassembly

!

ip nat inside source list 10 interface FastEthernet0/0 overload

!

access-list 10 permit 192.168.2.0 0.0.0.255

access-list 100 permit tcp any host 192.168.2.2 eq 3389

access-list 100 permit icmp any any

access-list 100 permit tcp any any eq telnet

It sounds like your problem is on the Netopia since you can telnet to the cisco from the Netopia. Does it have a FW turned on?

I am starting to believe the problem is with the Netopia, but it's not the configuration. It must be an issue with the 4 port switch on that device. I'm going to try reverting it to factory default - that solution has been known to correct strange problems with the device.
