Only two portals can be connected and they both have to have the same tag. Therefore:
- If you have one portal in your base called X and you make a portal somewhere else and call it X they'll be connected. If you change the later portal to Y they'll be disconnected.
- If you have 2 portals tagged as X and you open a new one and tag it X as well, the latest two to be tagged will be connected and the first will be disconnected.
- Tags are case sensitive.
- Tagless portals connect with each other as if the tag was no tag, but the same rules of having a tag apply.
- Connections take a few seconds to apply.
