Example value: GB
For more information on the ISO 3166-1 Alpha 2 format, refer to ISO 3166-1 Alpha 2 ↗ on Wikipedia.
For Magic Firewall, the ip.geoip.country field (which is deprecated) will match on either source or destination address. The ip.geoip.country field is still available for new and existing rules, but you should use the ip.src.country and/or ip.dst.country fields instead.

The length of the IPv4 header in bytes.
Example value: 5
ip.len Number 
The length of the packet including the header.
Example value: 60
ip.opt.type Number 
The first byte of IP options field ↗, if the options field is set.
Example value: 25
ip.proto String 
The transport layer for the packet, if it can be determined.
Example values: icmp, tcp
ip.src IP address 
The source address of the IP Packet.
ip.src.country String 
Represents the 2-letter country code associated with the client IP address in ISO 3166-1 Alpha 2 ↗ format.
Example value: GB
For more information on the ISO 3166-1 Alpha 2 format, refer to ISO 3166-1 Alpha 2 ↗ on Wikipedia.
ip.ttl Number 
The time-to-live of the IP Packet.
Example values: 54
sip Boolean 
Determines if packets are valid L7 protocol SIP ↗. Requires UDP packets to operate.
Use a guard clause as shown below to ensure the packet is UDP (wirefilter):
ip.proto == "udp"
tcp String 
The raw TCP packet as a list of bytes. It should be used in conjunction with the bit_slice function when other structured fields are lacking.
tcp.flags Number 
The numeric value of the TCP flags byte.
tcp.flags.ack Boolean 
TCP acknowledgment flag.
tcp.flags.cwr Boolean 
TCP congestion window reduced flag.
tcp.flags.ecn Boolean 
TCP ECN-Echo flag.
tcp.flags.fin Boolean 
TCP flag indicating this is the last packet from sender.
tcp.flags.push Boolean 
TCP push flag.
tcp.flags.reset Boolean 
TCP reset flag.
tcp.flags.syn Boolean 
TCP synchronize flag.
tcp.flags.urg Boolean 
TCP urgent flag.
tcp.srcport Number 
Source port number of the IP packet. Only applies to TCP packets.
tcp.dstport Number 
Destination port number of the IP packet. Only applies to TCP packets.
udp String 
The raw UDP packet as a list of bytes. It should be used in conjunction with the bit_slice function when other structured fields are lacking.
