#65: yakin bukan, soalnya didisconnectnya di level PPP. selain itu pakai ISP lain yang double NAT juga gak pernah ada masalah.

Mungkin effect double-natting? NAT dari anda dan si ISP juga.

You can actually change port range for the NAT in the 2.2/4 kernel Thus, detecting NAT by ports was never an efficient method. Lcamtuf’s p0f is quite a good method of detecting NATs but as you mentioned, it will not show different hosts behinde NAT if someone decide to share internet connectivity via Proxy (HTTP or SOCKS). Another good method is to tunnel traffic via SSH or SSL tunnels to external server, thus for specific services that are not using HTTP, you can use tunnels. Otherwise, you can modify kernel to send traffic that always looks the same. Oh, and I think your problem is related to configuration of your kernel , hardware problems or other issues. I think using p0f for big ISP networks is quite unlikely as there is totaly no point in use of it, as ISP implement traffic control per bandwidth and simply don’t care how many PCs are behind - the traffic rate always stays within limits. I’d advise you to analyse why your connection drops (in which point). There is a chance that your modem/router/firewall drops when you got higher traffic due to use of the network by 2 computers.

#59: rasanya bukan masalah MTU deh, saya juga sudah oprek MTU-nya.

Rasanya mungkin ini jawabannya NAT problem dan MTU setting. Mudah-mudahan berhasil seperti saya.

[...] Priyadi bilang bahwa ISP agak bertingkah. Kebetulan saya punya kasus yang mungkin serupa. Hanya saja di kasus saya, komputer share tidak bisa mengakses ke https. Mungkin ini bukan kesalahan ISP sepenuhnya. [...]
