Covid-19 Induced VPN Use -- security question

Hi,

I'm in the US and like a lot of people this week I'm scrambling to support people who usually work in one big room but are now telecommuting and making heavy use of our VPN.

Normally I have 3-10 connections per day, maybe 2-3 at a time, now I have 15-20 at a time (staff of 68). I think it would be more but by the time they get logged on I think it gets so slow they give up and find other avenues.

I already had IPS disabled for traffic to/from the VPN Pool and our LAN. But I noticed that I was still getting a flood of flood alerts in the IPS log about port 4500. I turned off IPS for all traffic over this port and over the L2TP protocol, regardless of it's source or destination.

Have I opened myself up to serious security concerns?

Thanks,

Jeff
