n****g 发帖数: 58 | 1 俺要写个presentation,要find a problem in ipv4 address, and solve it
大家说说都有啥热门的problem,谢谢
另外已经有人写ipv6了 |

other software traverse the nat and firewall? |

NAT)... no matter what you do on l2/l3, having a node with IP 10.1.1.1 to
talk to another node 10.1.1.1 end to end is a no go at IP stack, assume the

the incoming source on the target host... am not aware how people solve this

tagged, but when it hit the end node and get to |
g**d 发帖数: 77 | 4 not this one. i forgot the link. it is a hacker presentation in an europ
event on how to crack skype software. 1st part is how to decode, 2nd part is
a description how skype software communicate each other. 3rd part is how
they found a severe bug. |

m**t 发帖数: 1292 | 6 i was just mocking around, never mind
I feel the essence of those NAT traveral mechanisms remain same, i've run
into implementations of STUN, Mobile IP NAT traversal, HTTP Tunneling etc,
all of them needs a outsider service to be anchor point to relay or tunnel
packets. NAT has been such a pain in the butt
Come back to the original subject :) One of the tough problem I think is to
merge two networks with overlapping private IPv4 spaces without using NAT
gateways, anyone has idea on this?

p******h 发帖数: 1783 | 8 SIP based VOIP 不也是用STUN来穿透NAT的么?
Skype 的 p2p 比较起来就是用supernodes来替代一个中心server,这样理解对不对?

d*****y 发帖数: 260 | 16 You should also look at ICE draft and TURN internet draft.RFC 3489 has a
bias draft now since it is kind of
out of date, e.g., the classification of NAT types.
