SMC Networks SMC6224M manual ACL Configuration Extended IP

ACCESS CONTROL LISTS

For example, use the code value and mask below to catch packets with the following flags set:

-SYN flag valid, use control-code 2, control bitmask 2

-Both SYN and ACK valid, use control-code 18, control bitmask 18

-SYN valid and ACK invalid, use control-code 2, control bitmask 18

Web – Specify the action (i.e., Permit or Deny). Specify the source and/or destination addresses. Select the address type (Any, Host, or IP). If you select “Host,” enter a specific address. If you select “IP,” enter a subnet address and the mask for an address range. Set any other required criteria, such as service type, protocol type, or TCP control code. Then click Add.

CLI – This example adds two rules:

1.Accept any incoming packets if the source address is in subnet 10.7.1.x. For example, if the rule is matched; i.e., the rule (10.7.1.0 & 255.255.255.0) equals the masked address (10.7.1.2 & 255.255.255.0), the packet passes through.

2.Allow TCP packets from class C addresses 192.168.1.0 to any destination address when set for destination TCP port 80 (i.e., HTTP).
