Phantun aims to keep tunneling overhead to the minimum. The overhead compared to a plain UDP packet
is the following:
Plain UDP packet: 20 byte IP header + 8 byte UDP header = 28 bytes
Standard UDP packet: 20 byte IP header + 8 byte UDP header = 28 bytes
Phantun obfuscated UDP packet: 20 byte IP header + 20 byte TCP header = 40 bytes
Note that Phantun does not add any additional header other than IP and TCP headers in order to pass through
stateful packet inspection!
Phantun's additional overhead: 12 bytes. I other words, when using Phantun, the usable payload for
UDP packet is reduced by 12 bytes. This is the minimum overhead possible when doing such kind
of obfuscation.
