Hi,
I have some problems configuring the Cisco 1812 as IGMP proxy.
I have found instructions for configuring linux as router that handles the IGMP traffic. The config file for the IGMP-proxy in Linux looks like this:
quickleave
# upstream = Internet Device
phyint ppp0 upstream ratelimit 0 threshold 1
altnet 217.0.119.194/24
altnet 193.158.35.0/24;
# IP of Set-Top-Box
altnet 192.168.1.5/32;
# eth0 LAN-Interface
phyint eth0 downstream ratelimit 0 threshold 1
# other devices are deactivated
phyint eth1 disabled
phyint eth1.7 disabled
hyint lo disabled
Additionally the follwing commands need to be executed:
iptables -I FORWARD -s 217.0.119.0/24 -d 224.0.0.0/4 -j ACCEPT
iptables -I FORWARD -s 193.158.35.0/24 -d 224.0.0.0/4 -j ACCEPT
iptables -I INPUT -d 224.0.0.0/4 -j ACCEPT
iptables -I FORWARD -d 224.0.0.0/4 -j ACCEPT
Maybe you can help me converting this configuration for the 1812W (12.4)

Dear Vadim,
I'm using a switch to remove the VLAN tag for the Cisco Router and to tag the outgoing traffic with VLAN 7. Unfortunately I couldn't figure out how to configure PPPoE with VLAN tagging until today. I have found this document that describes the procedure: http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_guide09186a00801a8b6c.html
I will try to use this and if I suceed I will post the configuration.
Regards,
Alex

hi Alex,
Thats sound like a good idea :)
Let me know if youre finish.
Is your Router online ? ( With VDSL !?! )
I used the Cisco Feature Navigator - but i couldt find infos thats supports your 18xx the IGMP Proxy function. Only "UDLR Tunnel ARP and IGMP Proxy ".
best reagards

Hi Vadim,
I still didn't find the time to try the new configuration.
Currently my router works just fine with the little trick. Performance is excellent (50Mbit/sec).
As far as I know the router should support IGMP proxying, I already played around with it and it also shows some IGMP groups. I think the problems is that the firewall blocks some traffic. Maybe I have some time this weekend.

Alex

Hi Alex,
Can you please post your configuration
( Complete )? Thats would be great. Wich little Trick ? :)
I find this example for an 1802 Router:
vpdn enable
interface FastEthernet8
description WAN to VDSL-Modem
switchport access vlan 7
switchport mode trunk
interface Vlan7
no ip address
pppoe enable group global
pppoe-client dial-pool-number 11
interface Dialer11
description PPPoE to T-Online
ip address negotiated
encapsulation ppp
load-interval 30
dialer pool 11
dialer-group 1
ppp authentication pap callin
ppp pap sent-username Anschlusskennung+T-Online-Nummer# - eMail Adresse aus Sicherheitsgründen entfernt - password XXX
ppp ipcp dns request
But i dont cant use it :(
"switchport" is not support on my 2621 - i mean...
I have also a Catalyst 2950T. Can i create a VLAn 7 on the Catalyst - and then i plug my Modem on the Switch ? And The PPPoe neog. Comes "normal" from the Router ?

Hi!
The trick is removing the VLAN tag in the switch into the direction to the router and tagging it back to the modem. Then you can just configure the PPPoE connection as usual.
Unfortunately I'm so busy this moment that I can't play around with the other solution.
So my configuration is nothing special right now.
Greets,
Alex
