Though I have never worked on a backbone or ISP that did that, it might make sense to do it, and if someone has a problem, tell them to set up a pptp connection to their destination. Hrm, if microsoft is going to start multiplexing protocols to get past firewalls (DCOM et al..) maybe ISP's should insist users only use certain other protocols through an authenticated/encrypted tunnel? ;) Tit for tat, I say. Marcus Ranum had an interesting comment/platitude a while ago which was "de-muliplex HTTP!". This was in response to how vendors (one in particular) tunnel so much over http, which causes a number of access-control/security problems that break our attempts to add some semblance of security to IP networks. Maybe some protocols are only fit for VPNs? I say do it. However, you'll probably have to make a better business case for it than "Er.."batz" told me to.." -- batz Reluctant Ninja Defective Technologies
