In a subnet you may have addresses allocated for a number of reasons. The network and broadcast address, which are essentially wasted. Addresses for hosts that need full access to the internet. Addresses for hosts that need outbound connection to the internet but don't need incoming from the internet. Addresses for hosts that don't need internet access at ...

As commented, SNAT commonly refers to source NAT (usually NAPT, see RFC 2663) and shouldn't be used lightly for static NAT. Static NAT is used when the originating host is using a private IP address and you want to map a dedicated public IP address for Internet communication on a one-to-one basis. Static NAT is commonly used in server hosting, when the ...

If you use the following command, your problem will be solved. no ip dhcp snooping information option for example,my configuration: sw1-f1-msh-p#show run | s snooping ip dhcp snooping vlan 201,706,3200-3272 no ip dhcp snooping information option ip dhcp snooping trust

The problem is your handover subnet 77.5.6.20/30. It only allows two routers to attach (.21 and .22) - the ISP one and yours. No way to attach a third router. Of course, you could attach R2 behind R1 within the 88.10.1.0/27 subnet. R1 would then route transparently and only R2 would NAT your private subnet(s). As a side note, you really shouldn't run a ...

No, this wont work sadly. A router sits between networks and routes traffic between the networks. All you appear to be doing is creating two default gateways for subnets and configuring them on different routers. Because everything is using the same vlan 10 there is not way for the two routers to communicate with each other. If a PC with IP 172.18.10.55 ...

Basically, you take any single private or public network and you create multiple networks from it (to provide addresses for different locations, security zones, better scaling, ...). how [..] does that work when your network is assigned a single public IP? It doesn't. You need a network to start with. If for example my router's assigned public IP address ...

IP addresses from 224.0.0.0/4 are multicast addresses. They cannot be used as source address or for unicast. Unless you actually own the IP address range you might want to stick to RFC 1918 private addresses: 192.168.0.0/16, 172.16.0.0/12 and 10.0.0.0/8.

What we tried to do in the end was creating a list of all cisco routers where we noted for every one of them: IOS Software version System Image file used FPGA Version For those routers that had a connection problem, we found similarities in the IOS version, image file and FPGA version. In the end, what the local distributor of the cisco router found out ...

The cable can only be used between two devices, one on each end. The "adapter" you want is a switch on the upper floor, and you create a trunk between the two switches to separate the traffic from the different SSID, or you could have the same SSID with no trunk, but you would need to do something else to facilitate roaming (we do not have enough ...
