Hi Chris,

One of your phone numbers may be wrong - you have 8358662 on both sides.
I suspect the second 1750 number should be 8358663.

--- This is the 1750: <snip> dialer map ip 10.168.20.245 name R2-TermServ broadcast 8358661 dialer map ip 10.168.20.245 name R2-TermServ broadcast 8358662

This is the 2610 <snip> dialer map ip 10.168.20.246 name R8 broadcast 8358662 dialer map ip 10.168.20.246 name R8 broadcast 8358664

Hello everyone.

I have a 2610 with WIC-1B-U and a 1750 with WIC-1B-U. I configured them pretty much identically.

If they are configured in legacy DDR mode, the 1750 can call (via ping to remote IP) to the 2610 successfully 100% of the time. OK, that test is good. The 2610 on the other hand will simply bring up the interface, get through the authentication but never pass L3 (IP) traffic. No pings. I can see that PPP IPCP and CDPCP are up and running so this means I got through the PPP negotiation.

But if the connection is initiated by the 1750 I can ping both ways all day long.

But what really bugs the daylights out of me is if I convert to dialer profiles (dialer pool-member) it works 100% in both directions. Does anyone have any ideas as to why this may be happening?

Here are the snippets from both routers. They really are mirror images

This is the 1750:

interface BRI0 ip address 10.168.20.246 255.255.255.252 encapsulation ppp dialer map ip 10.168.20.245 name R2-TermServ broadcast 8358661 dialer map ip 10.168.20.245 name R2-TermServ broadcast 8358662 dialer load-threshold 50 either dialer-group 1 isdn switch-type basic-ni isdn spid1 0835866201 8358662 isdn spid2 0835866401 8358664 ppp authentication chap ppp multilink ! access-list 100 deny udp any any eq rip access-list 100 deny eigrp any any access-list 100 deny ospf any any access-list 100 deny ip 224.0.0.0 1.255.255.255 any access-list 100 permit ip any any dialer-list 1 protocol ip list 100

This is the 2610

interface BRI0/0 ip address 10.168.20.245 255.255.255.252 encapsulation ppp dialer map ip 10.168.20.246 name R8 broadcast 8358662 dialer map ip 10.168.20.246 name R8 broadcast 8358664 dialer load-threshold 50 either dialer-group 1 isdn switch-type basic-ni isdn spid1 0835866101 8358661 isdn spid2 0835866301 8358663 ppp authentication chap ppp multilink ! access-list 100 deny udp any any eq rip access-list 100 deny eigrp any any access-list 100 deny ospf any any access-list 100 deny ip 224.0.0.0 1.255.255.255 any access-list 100 permit ip any any dialer-list 1 protocol ip list 100

So tell me again. How do I set my laser printer to stun?
