@Talleyrand Then you can create Relay DHCP server where you can create different virtual subnet for the GVC. Follow the below KB for configuring the Relay DHCP server for the GVC.

@khuang Can you change the current WAN interface MTU value and try. For example if the current value is 1500, change to 1492 or lower and try. Or use the PMTU diagnostic tool to identify the MTU for your WAN interface.

@khuang Are you sure the 443 is the port you assigned to access the Firewall? Navigate to the Firewall-->System-->Administration & check the Web Management Settings.

@Pgmoftexas , Could you brief us your ISP connection in both location? Are you getting static IP in both location? If you dont mind share with us the configuration screenshot from both side.

@jtpryan I don't think so you can do the sonicwall migration tool to migrate TZ215 to TZ270. Best practice for this scenario you would have to configure the TZ270 from the scratch. Configuration Settings Import Support by Platform

@Jeong Which module is it?

@mike_yung, is there any free Firewall interface is available? your GVC DHCP Scope & LAN2 DHCP scope are same so you would have to assign different subnet DHCP scope for the GVC users. Follow the below KB. Let me know if you need further assistance.
