Usage:   filter [ filterlist = ]           [ srcaddr = ] (ipv4 | ipv6 | ipv4-ipv4 | ipv6-ipv6 | dns | server)          [ dstaddr = ] (ipv4 | ipv6 | ipv4-ipv4 | ipv6-ipv6 | dns | server)          [ [ description = ]  ]          [ [ protocol = ] (ANY | ICMP | TCP | UDP | RAW | ) ]          [ [ mirrored = ] (yes  |  no) ]          [ [ srcmask = ] (mask | prefix) ]          [ [ dstmask = ] (mask | prefix) ]          [ [ srcport = ]  ]          [ [ dstport = ]  ]    Adds a filter to the specified filter list.  Parameters:    Tag            Value   filterlist    -Name of the filter list to which the filter is added.   srcaddr       -Source ip address (ipv4 or ipv6), address range, dns name, or server type.   dstaddr       -Destination ip address (ipv4 or ipv6), address range, dns name, or server type.   description   -Brief information about the filter.   protocol      -Can be ANY, ICMP, TCP, UDP, RAW, or an integer.   mirrored      -‘Yes' creates two filters, one in each direction.   srcmask       -Source address mask or a prefix of 1 through 32. Not applicable if srcaddr is set to a range    dstmask       -Destination address mask or a prefix of 1 through 32. Not applicable if dstaddr is set to a range   srcport       -Source port of the packet. A value of 0 means any port.   dstport       -Destination port of the packet. A value of 0 means any port.  Remarks:  1. If the filter list does not exist it will be created.           2. To specify the current computer address, set srcaddr/dstaddr=me              To specify all computer addresses, set srcaddr/dstaddr=any           3. Server type can be WINS, DNS, DHCP or GATEWAY.           4. If source is a server type, then dest is 'me' and vice-versa.           5. If an address range is specified, the endpoints need to be specific addresses (not lists, or subnets) and of the same type (both should be v4 or both should be v6).  Examples: 1. add filter filterlist=Filter1 192.145.168.0 192.145.168.45           srcmask=24 dstmask=32           2. add filter filterlist=Filter1 srcaddr=DHCP dstaddr=0.0.0.0           protocol=ICMP srcmask=255.255.255.255 dstmask=255.255.255.255           3. add filter filterlist=Filter1 srcaddr=me dstaddr=any           4. add filter filterlist=Filter1 srcaddr= E3D7::51F4:9BC8:00A8:6420 dstaddr= ME           5. add filter filterlist=Filter1 srcaddr= 192.168.2.1-192,168.2.10 dstaddr= ME
