[SOLVED] Unable to load router/synology web pages on internal network

[Spies]

I cannot load the web interfaces for either my openwrt router or synology, both of which use nginx to serve the pages, is there any conceivable reason why this might be the case?

 

It happens in both my Windows 10 VM and MacOS VM, both using br0 for their network access.

 

I've done some searching, but most hits referring to issues to hosting an nginx server on KVM, not trying to load one from another networked device!

 

The Samba share on the synology hardly works from the VM also, whereas it works fine on another, baremetal machine without issue.

Turns out, it was because I had set an MTU lower than 1500 under Settings -> Network Settings, once set back to 1500, everything works again!
