• Ordering your rules is important because the p 793h v2 applies the rules in the order that you specify when a rule matches the current packet the p 793h v2 takes the corresponding action and the remaining rules are ignored if there are any empty rules before your new configured rule your configured rule will be pushed up by that number of empty rules for example if you have already configured rules 1 to 6 in your current set and now you configure rule number 9 in the set summary screen the new rule will be rule 7 not 9 now if you delete rule 4 rules 5 to 7 will be pushed up by 1 rule so old rules 5 6 and 7 become new rules 4 5 and 6 123

• Ip addresses and subnetting 463
• Ppendix 463
• Structure 463
• Figure 276 network number and host id 464
• Subnet masks 464
• Table 148 subnet masks 464
• An ip address with host ids of all zeros is the ip address of the network 192 68 with a 24 bit subnet mask for example an ip address with host ids of all ones is the broadcast address for that network 192 68 55 with a 24 bit subnet mask for example 465
• Appendix e ip addresses and subnetting 465
• As these two ip addresses cannot be used for individual hosts calculate the maximum number of possible hosts in a network as follows 465
• Binary 465
• By convention subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask followed by a continuous sequence of zeros for a total number of 32 bits 465
• Decimal 1st octet 465
• Nd octet 465
• Network size 465
• P 793h v2 user s guide 465
• Rd octet 465
• Subnet mask host id size maximum number of hosts 465
• Subnet masks are expressed in dotted decimal notation just like ip addresses the following examples show the binary and decimal notation for 8 bit 16 bit 24 bit and 29 bit subnet masks 465
• Subnet masks can be referred to by the size of the network number part the bits with a 1 value for example an 8 bit mask means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes 465
• Table 149 subnet masks 465
• Table 150 maximum host numbers 465
• Th octet 465
• The size of the network number determines the maximum number of possible hosts you can have on your network the larger the number of network number bits the smaller the number of remaining host id bits 465
• 2 or 254 possible hosts 466
• Alternative notation 466
• Appendix e ip addresses and subnetting 466
• For example 192 25 is equivalent to saying 192 with subnet mask 255 55 55 28 466
• In this example the company network address is 192 68 the first three octets of the address 192 68 are the network number and the remaining octet is the host id allowing a maximum of 466
• Last octet binary 466
• Last octet decimal 466
• Notation 466
• P 793h v2 user s guide 466
• Since the mask is always a continuous number of ones beginning from the left followed by a continuous number of zeros for the remainder of the 32 bit mask you can simply specify the number of ones instead of writing the value of each octet this is usually specified by writing a followed by the number of bits in the mask after the address 466
• Subnet mask 466
• Subnetting 466
• Table 151 alternative subnet mask notation 466
• The following table shows some possible subnet masks using both notations 466
• You can use subnetting to divide one network into multiple sub networks in the following example a network administrator creates two sub networks to isolate a group of servers from the rest of the company network for security reasons 466
• Figure 277 subnetting example before subnetting 467
• Figure 278 subnetting example after subnetting 467
• 2 or 126 possible hosts a host id of all zeroes is the subnet s address itself all ones is the subnet s broadcast address 468
• 2 or 62 hosts for each subnet a host id of all zeroes is the subnet itself all ones is the subnet s broadcast address 468
• 68 with mask 255 55 55 28 is subnet a itself and 192 68 27 with mask 255 55 55 28 is its broadcast address therefore the lowest ip address that can be assigned to an actual host for subnet a is 192 68 and the highest is 192 68 26 468
• Appendix e ip addresses and subnetting 468
• Each subnet contains 6 host id bits giving 468
• Example four subnets 468
• In a 25 bit subnet the host id has 7 bits so each sub network has a maximum of 468
• Ip subnet mask network number last octet bit value 468
• P 793h v2 user s guide 468
• Similarly the host id range for subnet b is 192 68 29 to 192 68 54 468
• Table 152 subnet 1 468
• Table 153 subnet 2 468
• The previous example illustrated using a 25 bit subnet mask to divide a 24 bit address into two subnets similarly to divide a 24 bit address into four subnets you need to borrow two host id bits to give four possible combinations 00 01 10 and 11 the subnet mask is 26 bits 11111111 1111111 1111111 11 000000 or 255 55 55 92 468
• Appendix e ip addresses and subnetting 469
• Broadcast address 469
• Example eight subnets 469
• Ip subnet mask network number last octet bit value 469
• P 793h v2 user s guide 469
