Router - ISP supplied - these are enabled by default - should I disable any?

Nothing fancy goes on here and Im wondering are any of these a security risk?

WAN Blocking

IPSec pass through

PPTP pass through

WAN Blocking - disables certain services from being enabled and accessible to people on the internet.  Leave it on unless you have issues you're trying to troubleshoot.

IPSec Pass-Through - allows you to connect to IPSec VPNs on the internet.  Won't cause any harm.

PPTP Pass-Through - as above but for PPTP VPNs.

Multicast - Allows streaming from your ISP (if streaming services are available direct from the ISP).  Again, won't cause an issue.
In theory you should close any services/passthroughs you don't need. (kinda like securely blocking up an old door you have no intention of ever using.)

if you don't need VPN dialin, you can disable IPSEC & PPTP passthrough to make sure that traffic is completely ignored.
It's not a major security risk though as it probably doesn't passthrough to anywhere anyway if you haven't enabled it on any of your servers.

Multicast doesn't cause any security issues so doesn't really matter too much for you.

WAN blocking is fine to leave on, but remember to include it in any diagnosis if anything doesn't work in the future. If turning that off fixes a future issue you can reassess if you want it enabled or not.
