I've a pb on my router that often comes to CPU 100 %.
After troubleshoot, i've found that this pb is due to "interrupts" and I suspect my NAT rule to be not enough restrictive or false.
What I need to do is to send UDP trafic (port 5060-5070) to IP A from IP B trough IPsec tunnel, and for this to work I need to NAT IP B to IP C.
Many thanks if you can help.
