Regards, I have Cisco 1812 connected to ISP's router Cisco 870. Both routers have switch module and when I'm connected with PC to 870 I can connect via VPN to remote location. When I'm connected to 1812 remote VPN doesn't work. Client computers are connected to 1812 and they can surf on internet just fine. Cisco 870 DHCP scope is 192.168.1.0/24 Cisco 1812 DHCP scope is 192.168.2.0/24 Cisco 870 and Cisco 1812 are directly connected via 213.147.xxx.182/30 and address on outside interface od cisco 870 is 213.147.xxx.99. I also have configured site2site VPN via 1812 which is working just fine. I tried changing MTU but nothing helps ... View more

Dear experts, Please be so kind and take a look at my configurations and problem. I need to configure Cisco 2811 (modem pvdm2-36D, E1 PRI) as RAS for dialin and dialout DDR to 250 remote locations (analog modems) with different usernames and passwords. I managed to configure dialin where authentication is done via radius and that works flawless but I'm confused with how to configure DDR on same device. Remote locations authenticate with radius and get their static IP addressess via radius too. Please give me suggestions/examples. ---------------------------------------------------------------------------------------- My current configuration: card type e1 1 ! aaa new-model aaa authentication ppp default group radius local aaa authorization network default group radius aaa session-id common clock timezone UTC1 1 clock summer-time MET-DST recurring last Sun Mar 2:00 last Sun Oct 2:00 network-clock-participate slot 1 network-clock-select 1 E1 1/0 ! modem country v12 e1-default no ip source-route ! isdn switch-type primary-net5 ! controller E1 1/0 pri-group timeslots 1-31 ! interface FastEthernet0/0 ip address 192.168.1.125 255.255.255.0 duplex auto speed auto ! interface Serial1/0:15 no ip address encapsulation ppp isdn switch-type primary-net5 isdn incoming-voice modem no cdp enable ! ! interface Group-Async1 ip unnumbered FastEthernet0/0 encapsulation ppp async mode interactive ppp authentication pap group-range 0/322 0/357 ! ! ip route 172.16.0.128 255.255.255.128 10.10.0.2 -> ip route to remote location 1 . . . ip route 172.16.201.0 255.255.255.128 10.10.1.214 -> ip route to remote location 250 ! ! line 0/322 0/357 no flush-at-activation login local modem InOut modem autoconfigure discovery transport input all transport output all autoselect during-login autoselect ppp ---------------------------------------------------------------------------------------- This is my configuration for dialin and DDR dialout but it doesn't work.

Greetings to all readers, I recently implemented dialin RAS with Cisco 2811 pvdm2-36DM E1 with VPDN and Radius. I also want to configura dial on demand on same device for 300 remote locations. I tried to do that with Dialer interfaces but ping works sometimes, sometimes it doesnt work and I'm quite confused :| Here's an example of my dialer interface interface Dialer2 ip unnumbered Loopback2 encapsulation ppp dialer remote-name REMOTE-NAME dialer idle-timeout 900 dialer string XXXXXXX dialer-group 1 no cdp enable ppp authentication pap ppp pap sent-username USERNAME password 0 PASSWORD end When I try to ping that location I sometimes get: C:\Documents and Settings\admin>ping REMOTE-NAME Pinging REMOTE-NAME [192.16.1.1] with 32 bytes of data: Reply from 192.16.1.1: bytes=32 time=461ms TTL=124 Reply from 192.16.1.1: bytes=32 time=75ms TTL=124 Reply from 192.16.1.1: bytes=32 time=71ms TTL=124 Reply from 192.16.1.1: bytes=32 time=74ms TTL=124 and the next time I get: C:\Documents and Settings\admin>ping -n 100 REMOTE-NAME Pinging 192.16.1.1 with 32 bytes of data: Reply from 78.3.112.38: Destination host unreachable.

dear colleagues, I have configured Cisco 2811 RAS with E1 for dial in access for several remote locations which have analog modems.
