Openvpn config to allow IGMP traffic?

[flipthetip]

Im not pretty sure if i got the title correctly but here's my point.
I use my VPN to browse the internet. Lately, my ISP implemented IGMP and now I cant connect to the internet thru my VPN.

I checked google and some routing should be done though im not sure how to do it.
Any suggestions guys?
Any help will be warmly appreciated. thanks!

Without any info on configuration - can't help. May be asking the ISP about changes they maid?

I am not sure this is the problem. New versions allow UDP multicast and IGMP packets.

about the changes.well new rollouts are normal,now all vpn clients that we currently use,cannot push thru.
even browsing the internet thru the vpn cannot be done since the IGMP changes. any suggestions?

Your OpenVPN server has a real IP?
Could you post some traceroute to 8.8.8.8?
Could you post the logs from client and server?
Are the pushed DNS accesible from cleint? ie a nslookup.

im not sure,how i can answer your questions.
but the logs are pretty normal.
still the same when things were still working, i can even go to my webmin page when im connected to the vpn,and i can also ping my IP.

i think this can be fixed thru some routing.
what do you guys think?
