How to add 2VLAN connection to a Port in a Managed Switch?

Model: T2600G-52TS(TL-SG3452)Hardware Version: V3Firmware Version:

Hi, 

So we have 1 Managed switch to Bldg. B, and an Unifi UAP-AC-PRO setup with VLAN30 and VLAN40 option.

Our Local LAN is 10.10.6.x 

VLAN 30 is 192.168.30.x

VLAN 40 is 192.168.40.x

We do have 2 internet connection 

Default Gateway 1 is 10.10.6.10

Default Gateway 2 is 10.10.6.9

We added the 2 default gateways  and set an IP of 10.10.6.245 for the Managed Switch.

I can ping the Access Point but no internet

Maybe adding the VLAN30 and VLAN40 to the Port where the Access Point was plugged can solve the problem.. but can you add 2VLAN in a Port?

Any tips on setting this up? Thank you
