Да.Отговор с да/не също ме удовлетворява. i486 100-120mhz ще понесе ли криптирането( 3DES?) за 64Kb канал , по който ще върви тунела?
Тriple DES implementation as 928 Pentium cycles per block, or 116 per byte. Adding that to the 24 above, we get 140 cycles per byte for IPsec with encryption. At 140 cycles per byte, a 140 MHz machine can handle a megabyte -- 8 megabits -- per second. Speeds for other machines will be proportional to this. To saturate a link with capacity C megabits per second, you need a machine running at C * 140/8 = C * 17.5 MHz.
