This is because we want connection requests to any Resource to be as simple as possible for the end users: when they connect to a particular IP address or FQDN, Pangolin figures out which site to send it to and the end user never needs to figure this out. -It is recommended that you create overlapping resources only if absolutely required.

Right now, ICMP **is not supported** through the Pangolin client. If you need to ping hosts on the remote network, consider using TCP or UDP-based tools like `hping3` or `nping` as alternatives. We plan to add ICMP support in a future release. + +## Unicast Only? + +Right now unicast TCP and UDP traffic is supported through the Pangolin client. Multicast and broadcast traffic is not supported at this time.
