RB2011 Simple VLAN setup

Hi,
I have to setup a router for a small hotel with a guest wifi. I’m new at mikrotik and also to VLAN, so I been trying to figure it and I spend a lot of time just to get lost in so many options and scenarios…
Also it’s posible in the future we’re going to need Dual-WAN for failover and balance but right now leave the Wan2 port unused would be enough.
The hotel used to have:

  • Linksys E2500 Router, WAN: DHCP, LAN: 192.168.0.1
  • D-Link DES-3026 switch, not sure if it’s setup to defaults or not
  • VoIP Telephone system (recent installation, and manage by other guys),
  • 2 Bullet antennas for the guest and office Wifi. One of those had recently fail.

We had installed yet:

  • RB2011UiAS-RM, WAN: DHCP, LAN: 192.168.88.1
  • 13 U-AP and some switches, due to hotel distribution. UAP’s IP not static but reserved.
  • I’ve keep the E2500 temporary to have separated networks for guest and office
  • I found in forum and wikis how to setup DynDNS and add rule in firewall to allow remote access to the RB2011.
  • Took off the remaining Ubiquiti Bullet.

The goal:

  • Since Office have wired and wireless devices and Guest only access through wifi, I guess VLan for Guest to keep isolated form office network could be the way.
  • About Dual-Wan is not needed immediately.
  • Keep the Office network at 192.168.0.1 because of the VoIP system.
