RE: [p2p-hackers] I hate SPI Firewalls

It’s my understanding that firewalls employing deep packet inspection work like any other, except also use the contents of the packet (or stream of packets) in their filtering decisions.  Thus I’m not sure they really deserve special treatment, unless you find that your protocol is being specifically targeted by admins.  And if so, you might want to tunnel over SSL or SSH or some other encrypted protocol that probably isn’t blocked.

 

What specifically are you seeing in the field that’s mucking you up?

specifically...do SPI firewalls use a different port number for each new destination ip address? Or do they actuall check the packet; or is it determined by vendor?

 

thanks

Do you specifically mean how to impersonate other protocols so as to avoid SPI (stateful packet inspection, I assume) firewalls?  Or is there some more “correct” way, such as UPnP?

does anyone know where i can obtain easy documentation on how to punch and maintain a hole through SPI; any helpful hints?

 

i'm having problems with Netgear Routers.

 

thanks.
