I don't expect my isp to run stuff on their router any more than I expect my isp to block stuff. I don't know everything about igmp since hardly anyone I know uses it (I don't work at an ISP though) but If i send packets with the ipheader->protocol field set to igmp (2 I think) destined for another computer on the internet I don't expect you to drop it (I know this is silly because IGMP doesn't work that way). I don't see the point to this. What you are talking about is routing multicast not wheter you are filtering out certain protocols. There is a diffrence with not supporting something and filtering something out without a reason. I can see that for an isp to route multicast it cost extra money for the customer since you have to configure a lot of shit on your side but what we are talking about is the opposite. If you/ISP is going to filter out protocols you need to configure access lists or something for no good reason except to piss the customer off. //Magnus On Wed, Jun 19, 2002 at 09:15:14AM +0100, Stephen J.

Hello,
multicasting has nothing to do with ipheader->protocol as far as I know. So my definition doesn't consider multicasting.

I dont provide multicast, am I not an ISP by your definition? I think so..

Thus spake "Magnus Boden" <mb@ozaba.cx>
I wouldn't call it an isp if they only allowed tcp, udp and icmp. It should be all ip protocols.
There can be a maximum of 256 of them. The isp shouldn't care what the ipheader->protocol field is set to.
There is at least one ISP here in the US that filters protocol 50 (IPsec ESP). Does that mean they're really not an ISP?

They can still call themselves whatever they want, but I wouldn't consider them an ISP, as they're not provider a very key part of my "Internet experience". I'd feel the same way if they filtered google.
