4. Adjusting the Sequence of TTL Rules
After configuring multiple TTL rules, you can adjust their sequence to specify the rule matching sequence. TTL
rules in front rows are matched first, and those in back rows are matched later. If the ranges of rules overlap, the
final effect is the superposition of multiple matching results.

Choose Local Device > Advanced > Other Settings.
You can set some functions not frequently used on the Other Settings page. By default, all the functions on this
page are disabled.
Enable RIP&RIPng: After this function is enabled, LAN and WAN ports support dynamic routing protocols Routing
Information Protocol (RIP) and RIP next generation (RIPng) and can automatically synchronize route information
from other RIP-enabled routers in the network.
Enable SIP ALG: Some voice communication uses the Session Initiation Protocol (SIP) protocol. If the server is
connected to a WAN port, SIP packets may become unavailable after NAT. After you enable this function, SIP
packets are converted by the application-level gateway (ALG). You can enable or disable this function based on
actual needs.
