Access Server, IP comunication PROBLEM!

agonzalez

I´m setting up a Access Server wiht Cisco 2612 with a 16-NM-AM and a Token Ring Interface.

I were able to dial-in from remote location using windows dialup and getting an ip address from central site from the assigned DHCP Server (windows based).

The BIG problem I´m facing now is that my remote

user can´t reach any host into my network.

If I ping any host into the network, the router trys to get the IP address of my LapTop via ARP in all interfaces including the asyn interface where I´m conected, but the router never knows where I´m attached (I use the ICMP debug), now if I use the show ip arp command my IP address appears but it says incomplete.

IP address Interface

x.x.x.x incomplet

like the router never knows where I´m connected

The router can reach any local host in the network!

Any suggestion or any tip???

version 12.2

dialer-list 1 protocol ip permit

interface Group-Async1

ip unnumbered TokenRing0/0

ip helper-address 10.110.4.C (DHCP Server)

encapsulation ppp

dialer in-band

dialer idle-timeout 600

dialer-group 1

autodetect encapsulation ppp

async mode interactive

peer default ip address dhcp

ppp authentication chap

group-range 33 48

!

line 33 48

login local

modem InOut

transport input all

autoselect ppp

flowcontrol hardware

Is something wrong? I hope you can help me!

Thanks in advance!

Can you please post the debug outputs of "deb ppp nego", will like to see the IPCP negotation.

Just for the sake for testing, can you try the following:

1)conf term

int loop 0

ip address 1.1.1.1 255.255.255.255

int group-asyn 1

ip unnumber loop 0

peer default ip address pool addr-pool <===assigning ip address locally instead of dhcp

ip local pool addr-pool 10.1.1.1 10.1.1.50

After the ip address negotation is completed, do

"sh ip route x.x.x.x" where x.x.x.x is the ip address assigned from the pool.

Also ensure you have "ip routing" enabled.

Thanks, Mak.

I just want to know why the ip address of the asyncs interfaces must be diferent from local LAN

I just work with your tops and it work well!
