- Lack of filter/firewall on incoming traffic across IPSEC VPN. Just as often as I setup site-to-site VPN's for two offices within a company, I am asked to setup a site-to-site VPN with a third party. I can never implicitly trust the third party so I have to get a cisco or sonicwall device to do the VPN so I can filter incoming traffic.
