First time with a Mikrotik and not a network wiz so I apologize in advance. I’m configuring a CRS310 for homelab and everything was working when I was behind my existing UNIFI router. When I simply move the WAN port to the starlink router directly I start to encounter issues. I can still ping just fine and everything I tried is reachable however web browsing is extremely slow, pages partially load, or I get a “PR_END_OF_FILE_ERROR” message.
reading other posts I adjusted the MTU down to 1400 even though pings with a size of 1500 worked fine. I finally blew it away and used the Quick Set button and the results are exactly the same.
I can keep my PC plugged into ether2 and move ether1 from the starlink to the UNIFI and everything will instantly start working. Starlink gives out a 192.168.1.X IP to the Mikrotik and UNIFI gives out a 192.168.100.X IP if this matters for any reason. When daisy chained through the UNIFI a fast.com speed test is showing 120mb down, 10mb up, and 30ms loaded which is normal for my location.
Any help with troubleshooting would be greatly appreciated.
