Buffalo WHR-HP-G300n. Running OpenWRT LEDE 18.06.1.
4 vLANs configured. 3 vAPs configured. Each vLAN is bridged to it's corresponding vAP, except for the "Management" vLAN. All vLANs are connected to a single uplink port, in a "trunk" configuration.

From my laptop on my "Private" vLAN (vid=24), I can connect to the AP on that interface via SSH and not have any issues. I ultimately want to only have a configuration IP on the "management" vlan (vid=200). When I try to connect with my laptop to the management interface of the AP, the connection drops after 20-30 seconds.
I doubt I have a routing issue, since I'm able to hold a connection to any other device in the management interface.
I've even created a debian VM and placed it on the management interface. It can connect to the management interface on the AP without issue as well.
I'm a bit stumped. Any ideas?
Edit:
I just ran a 'netstat -n' on the buffalo router. My laptop (10.10.24.100) only has one SSH client session running. Why is the AP showing an active connection from my laptop to it's management interface?
root@ap-buffalo1:~# netstat -n
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 27852 10.10.200.51:22 10.10.24.100:58322 ESTABLISHED
tcp 0 304 10.10.24.51:22 10.10.24.100:58319 ESTABLISHED
It's gone now.. The connection timeout must have taken a bit to be reflected in netstat. This is seeming more and more like a routing issue, not on the AP itself.
