Route Table Contents

View the firewall route table at Diagnostics > Routes.

Each line shows the destination network, gateway by which it can be reached, route flags, number of references and times the route has been used, the MTU, the interface through which the routed traffic will be sent by the firewall.

The list of routes supports pagination and filtering to aid with viewing large routing tables such as those found with a full BGP feed.

Resolve Names

When checked, the firewall attempts a DNS lookup to show hostnames rather than IP addresses for route table entries. This will cause a delay and performance penalty.

Rows to display

By default the page displays 100 rows. Choose a new value to show more or less rows.

Filter

Search the route table for entries matching this string. The field supports regular expressions for advanced filtering.

Click fa-refresh Update to redisplay the routing table with the current settings.
