My ISP is Comcast and I am assigned a range of 5 external IP addresses.

How can I determine which external IP address the SonicWALL VPN is using so that when I configure the VPN clients on Windows 10 computers I will put in the right external IP address?

The SonicWALL router is a TZ600.

Or log into the Sonicwalls managment page and look under the interfaces section. One interface should have WAN as a name or description.

Log on to the management console and click into the VPN section (left hand column). When set up it should identify the port assigned. The IP on that port should be listed in Network above.

SonicWalls always use X1 IP (Or what ever port your WAN is) for VPN

If there is a network definition on the outside interface (multiple addresses), also check the output source nat specifications.
OR from system behind the firewall use whatsmyipaddress.com ... Like soulja told.

Generally speaking, what Soulja cited should work.

My ISP is Comcast and I am assigned a range of 5 external IP addresses.
I tend to recommend creating a DNS record for this so that there is something easy to remember. Bear in mind that this does become something additional to manage.
