If you restrict IP access to the Plesk control panel and you try connecting from an IP address not in the accepted access list you will receive an error message along the lines of:

Error: Access for administrator from address ‘192.168.1.1′ is restricted in accordance with IP Access restriction policy currently applied.

If you can SSH into the machine you can add this new IP address to the access list manually.

bash# mysql -uadmin -p`cat /etc/psa/.psa.shadow ` psa

mysql> insert into cp_access values (“”, “deny”, “192.168.1.1″, “255.255.255.255″);
Query OK, 1 row affected, 1 warning (0.02 sec)

Then you should be able to connect to the Plesk control panel from the new IP address.
