Cannot access Management Console due to changed IP address

[RevolveIT]

We have a client's 3cx Debian instance hosted with Binary Lane. We previously locked the management console down to allow login from our office WAN IP. Unfortunately our ISP had an issue they couldn't resolve internally which forced us to change our WAN IP. Now we cannot access the management console and instead get the following message:

"Login access denied. Too many incorrect login attempts. Try later or contact the Administrator."

How can this be resolved? There is no local access other than by SSH (we still have root access). There is a backup taken 5 days ago, but this will contain the same IP restriction.

Can anyone help?

Thanks for that - I managed to get in using that guide as a reference. I wasn't able to connect the first time, but that was due to not having a private LAN IP attached to the network interface in our Debian install. Our /etc/network/interfaces file was as follows:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug ens3
iface ens3 inet dhcp

And to get it to work for us we changed it to:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# allow-hotplug ens3
# iface ens3 inet dhcp

auto ens3
iface ens3 inet static
address [PUBLIC IP]
netmask 255.255.255.0
gateway [PUBLIC GATEWAY IP]
broadcast [PUBLIC BROADCAST IP]

auto ens3:0
iface ens3:0 inet static
address [PRIVATE LAN IP]
netmask 255.255.255.0

After this, I was able to use Putty to SSH tunnel to the private LAN IP, log into the admin console and temporarily change the console restrictions to "Allow Access from everywhere", before adding in our new IP's
