Conflicting docker containers in unraid.

[rocklord2004]

I'm new to using unraid and decided to run dedicated servers through the docker function. 7 Days to Die works fine if it's the only one but when I start up Valheim anybody not on my local network has desync issues that make it unplayable. If I turn off the Valheim container performance improves significantly. I'm assuming I actually need to make some kind of change in my router but I'm not sure what to look for. I gave the computer traffic priority and checked for conflicting ports. I searched in the forums for similar issues but didn't find them. If there is a solution already posted I welcome being directed to it.
