I setup a 1.231 monowall with IPsec VPN between 2 sites, but a warning : pseudo-random number generator used for IPsec processing always pop up on the monowall terminal.

Anyone know what is wrong on my monowall setup ??

Nothing wrong.

It's just warning you that no software can generate truly random numbers, which means your encryption is theoretically potentially easier to crack. Unless you have a HUGE target on you (read: somebody with millions of dollars of cracking equipment is after you), ignore it.

If you're super paranoid, buy a hardware crypto card, which will generate truly random numbers. Personally, I would just ignore it. 99.99999999% of us aren't remotely interesting enough to justify the cost and effort of cracking IPsec, pseudo-random numbers or not.
