  • It's likely that you have IPS configured incorrectly.  Make sure that 'Local networks' includes only "Internal (Network)" and "DMZ (Network)" - and maybe any "VPN Pool (?????)" in use.

    I made the mistake once myself of putting "External (Network)" in 'Local networks' and had the same lockups you're experiencing.  I imagine it would be even worse if "Any" is in there.

    Was that it?

    Cheers - Bob
