I updated my CBOS to 2.4.6 and decided to enable the filters to lock down the unit. Now the IPSec clients (Nortel Contivity) can't connect. I have enabled UDP port 500, and it is working up until the client starts to send ESP packets over IP protocol 50. The server respose never appears on my analyzer.
I am assuming the default "Deny All" is doing just that but can't find a way to ALLOW IP protocol 50. Any ideas out there?
Re: IPSec breaks over NAT after 675 filters enabled
Went over that pretty thoroughly. I finally got it work by doing an ALLOW ALL incoming and outging and the bottom of my list, but i would prefer the explict allow. For it will work as the inside FW will do most of the protection, but it would be nice if CBOS recognized protocols other than just TCP/UDP/ICMP
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
