Async routing

[COMPUTERTECH33]

Hi all....

I have a 1750 with a modem attached to the AUX port. I assigned the Async5 with an ip of 170.1.1.16. It can dial into my 3640 fine...and the router can ping all external and internal ips. The problem is, I have a client connected to the router that can't ping past the router. Any ideas?

interface Async5
ip address 170.1.1.16 255.255.255.0
encapsulation ppp
keepalive 10
dialer in-band
dialer idle-timeout 300
dialer string 9,xxxxxxxxxx
dialer-group 1
fair-queue 64 16 0
ppp authentication chap

ip route 0.0.0.0 0.0.0.0 Async5 200

access-list 110 deny ip 192.168.17.0 0.0.0.255 172.16.0.0 0.0.255.255

Does the 3640 have a route to the networks behind the 1750?

Yes...the 3640 can communicate to the internal network. Other users can currently dial in from their laptops and connect to our network without issue.
