Motorola Enterprise Series Routers 사용자 설명서

Maximum Packet Size permits you to modify the MTU setting for the tunnel. Some ISPs require a setting 
of e.g. 1492 (or other value). The default 1500 is the most common and you usually don’t need to change 
this unless other wise instructed. Accepted values are from 100 – 1500.

This is the star ting value that is used for the MTU when the IPSec tunnel is installed. It specifies the 
maximum IP packet length for the encapsulated AH or ESP packets sent by the router. The MTU used on 
the IPSec connection will be automatically adjusted based on the MTU value in any received ICMP can't 
fragment error messages that correspond to IPSec traffic initiated from the router. Normally the MTU only 
requires manual configuration if the ICMP error messages are blocked or other wise not received by the 
router.

You can also configure IKE Phase 1 Profiles in the WAN Configuration menus.

The WAN Configuration screen now includes IKE Phase 1 Configuration as shown:
