You can filter incoming activity by IPv6 address from the Dynamic Filtering - Incoming IPv6 Address Security screen. To reach the screen, select 2. Incoming IPv6 Addresses from the Work with Dynamic Filtering screen(STRFW > 2 > 2).

The Dynamic Filtering - Incoming IPv6 Address Security screen appears.

The screen shows existing rules for filtering activity coming in via various protocols from specific IPv6 addresses. The entry for *ALL shows general rules for incoming activity coming from IPv6 addresses that are not listed.

Each of the other lines shows rules for ranges of IP addresses, shown by a specific IPv6 address and address prefix length. The following columns show the rules for specific protocols, as shown by the vertical text at the top of each column:

  • FTP including FTPLOG and REXLOG
  • Telnet
  • DB including SQLENT, SQL, NDB, OBJINF, and DBOPEN
  • TCPSGN, the TCP Sign-On Server
  • RMT, for Remote Program/Command Call
  • DDM including DRDA
  • Fil Srv, for File Server

For each protocol, the letter in that column shows how the rule handles incoming activity for that protocol from that IP address range:

  • Blank or N: Reject all incoming activity
  • S: Allow activity, but do not log this
  • Y: Allow activity

The final Text column shows a freeform text description of the rule.

To modify an existing rule, enter 1 in the Opt column for that rule. The Dynamic Filtering- Modify Incoming IPv6 Address screen appears, as shown in Modifying a Firewall Rule for Incoming Activity by IPv6 Addresses

To add a new rule, press the F6 key. The Dynamic Filtering- Add Incoming IP Address screen appears, as shown in Adding a Firewall Rule for Incoming Activity by IP Address.
