frozer,
Тут я с вами не соглашусь и поспорю

1
{DNS:60, UDP:59, IPv4:8} - IP-лок - IP-DNS - DNS:QueryId = 0xE3AB, QUERY (Standard query), Query for mail.ru of type Host Addr on class Internet
2
{DNS:60, UDP:59, IPv4:8} - IP-DNS - IP-лок - DNS:QueryId = 0xE3AB, QUERY (Standard query), Response - Success, [217.69.128.45, 217.69.128.41 ... ]
3
{TCP:58, IPv4:2, IPv4:11} - IP-serv-vpn - IP-лок - SrcPort=HTTP(80), DstPort=52593, PayloadLen=0, Seq=3102319310, Ack=3439881161, Win=65535 ( Negotiated scale factor 0x1 ) = 131070
--Gre: Protocol = PPP, Flags = ..KS....A....... Version 1 , Length = 0x41 , CallID = 0x2e2e
----Ipv4: IP-vpn-кл - 217.69.128.45, ....
4
{TCP:4, IPv4:3, IPv4:11} - IP-serv-vpn - IP-лок - SrcPort=HTTP(80), DstPort=52615, PayloadLen=0, Seq=3462097665, Ack=2005666816, Win=7974 (scale factor 0x0) = 7974
--Gre: Protocol = PPP, Flags = ..KS............ Version 1 , Length = 0x35 , CallID = 0x2e2e
----Ipv4: 217.69.128.54, IP-vpn-кл, ....

и т.д.

В 1 и 2 пакетах вообще тунеля нет и GRE тоже.
