How To Switch Between 5 New Static IP Addresses
Apr 28, 2013
how to switch between my 5 new static IP addresses that I purchased (on a monthly basis now) from my ISP. I need them for my business so that I can send out more than the 1,000 emails per day from the one IP address to all of my customers which total a little over 1,500 now. Unfortunately I'm quite computer iliterate when it comes to understanding even the basics of computer terminology, etc. My ISP explained to me that if I purchased the bundle of 5 static IPs, then I could in essence send out 5,000 emails per day, which is plenty.

I want to turn off DHCP and setup static IP addresses, but have some questions about applying the information to my specific system.I have a Cisco Wireless Router, 1-wired computer (windows 7) and 2-wireless computers (1-XP and the other is Windows 7). I also have a dual wireless print server, a Roku box, a Wii, a Kindle Fire, and Vonage which is connected between my cable modem and router (this was the preferred installation method by Vonage).I have ran IPCONFIG /All and have all the addresses. My concern is what to use as a static address for my router first off, and then how I go about picking IP addresses for the computers and devices, and how to set then up both at the router and at the computer or device. Also, do I need any IP address ranges for any of this? I'd also like to make sure it would be possible to setup this system with the Vonage adapter connected between the cable modem and router as it's setup now.

We have both a Comcast and Verizon connection at our school. They are going into a Sonicwall NSA5500. The configuration is such that if the primary - Comcast - fails then the secondary - Verizon - will pickup the internet traffic. The issue we are having is with local Verizon customers. When we got our IP address from verizon it was a /24 subnet with a gateway starting at .1
I thought this was strange as every other time I have gotten a block of static IP addresses from an ISP it has been a /29 or /28 at the most. But the ISP confirmed that this is what we were supposed to get and it should not cause problems.
A local business we deal with happens to be on our subnet with the same next hop Gateway. When I perform a traceroute to them, the traffic goes directly out the Verizon WAN interface to our common gateway, then to the local business. This, all while the Comcast Interface is our dedicated primary for all traffic.
I spoke with Sonicwall and they explained that the firewall is simply taking the most efficient path which makes sense to me in some regard but is still confusing why it would use the interface when policy says it is a failover.
Now, this local business tries to send us email with their on premise Exchange - we also have Exchange. The emails will sit in their queue indefinitely and ultimately fail to reach us. If I disable the Verizon interface the emails come in perfectly fine - even some in their queue will immediately come through once I disable it. I thought this was a DNS issue but it is not or at least our DNS is all configured correctly where we have no other problems with email. Our MX records utilize the static IPs from Comcast - nothing is using our static Verizon addresses.

I've installed RV042 for a client of mine. For next two months everything worked without any problems. The issue I've been experiencing lately is when I assign a static IP address to the PC it won't have internet access. Once I allow it to have a dynamically assigned IP then it works fine. The IP I assign isn't part of the DHCP range.

I used to use a CentOS self-made server for intranet for my little office, but I bouth few days ago a Cisco 861 router to replace the linux box.
1. I have 2 public IP classes from my ISP. 1 class is limitted to 80mbit upload, the other to 30mbit upload. So I need some sort of DNAT to be able to know exactly which intranet computer uses big internet and which one limitted internet.
2. I need DHCP server and with static IP addresses (one computer must always have the same IP address, etc).. i have my needs for this.
3. Also I need external access to some servers inside (web, ftp, etc) [code]
So far so good, all looks simple and I can achieve this in 2 hours on a centos linux box (correct routes, ip forwarding enabled and few iptables rules for NAT/SNAT/DNAT).
But on this brand new Centos router well, i'm not even successful in pinging the outside world, nor the inside world I'm tired of reading the forums, the documentation..i want (at first) a simple scenario: vlan+dhcp, fa4 with 1 public ip address and ACCESS to the real world. I wasn't able to achieve not even that much. [code]

I have an E3000 that I am just setting up.I have two issues:
1> I am replacing a WRT110. I had the old router set with a static IP address supplied by my ISP. I configured the E3000 with the same address and I cannot access the internet. Are there any tricks to setting this up on an E3000?
2> As configured I there is a guest network setup. BUT when I access the router I don't see the tab to be able to configure it.

I am trying to configure a BT Business ADSL Router (BT2700HGV) to work in bridge mode in front of a Cisco RV120W router and cannot get this to work.I have followed numerous posts I have come across in configuring the BT router for bridged mode and this has been configured as follows:
ATM Encapsulation - Bridge LLC
DSL and ATM - VPI=0, VCI=38 (also tried VCI=35)
ATM PVC Search - Disabled
Connection Type - Direct IP (DHCP or Static)
Disable Routing - Yes
There are also some other options on the same configuration page for 'Broadband IP Network' (which I have left on DHCP) and also a 'Public IP' which has been left blank. After setting the above options this removes the LAN DHCP configuration, the PPPoA logon details and sets the internal IP address of the BT router to 192.168.1.254.
My understanding of 'Bridge' mode is that this router will now act simply as a modem and configuration details such as logon details and WAN IP address information are configured using the Cisco RV120W router?The configuration of the Cisco router is as follows:
Internet Connection Type - PPPoE
Username and Password set
Authentication Type - Auto-Negotiate (options here are PAP, CHAP, MS-CHAP and MS-CHAPv2)
Routing Mode - Router (Other option is 'Gateway (NAT))' - I have tried both options
The WAN interface on the Cisco router is connected to one of the LAN ports on the BT router. The 'Broadband' light is on the BT router but the 'Internet' light isn't. The WAN status on the Cisco router is 'Connecting'. I am sure I am missing something simple.We have been assigned a range of static IP addresses from BT so am trying to get these working too (x.x.x.24/29 - 5 usable statics), another option available (other than PPPoE) for configuring the WAN interface on the Cisco router is a 'Static IP', not sure if this is the correct option but have tried messing with it, I have tried assigning a static IP from the range given to us (.30 - the router address specified by BT) along with the subnet mask, however don't know what to put as the default gateway, would this be the peer address (but assume that would change anyway), in any case, using the 'Static IP' option does not give an option to supply the BT logon details which I assume is required?
In bridged mode, what is the peer address assigned to, the BT router or the Cisco router?Does the BT router need to be configured with a public IP address?

I upgraded my SG500 switch firmware to 1.3.0.59, since there is a new functionality DHCP server v.4 well I must say I came accross the issue I cannot solve. DHCP server assign dynamic address - no hassles. troubles start with static IP hosts.I defined a couple of hosts with static address within the correct subnet. I tried with hardware address and client identifiers. no luck. my switch does not assign the IP address I assigned to the suitable mac address. to define it I use both CLI & Web.
ip dhcp pool host HP-Elliteaddress 10.10.11.7 255.255.255.0 client-identifier 01:d8:d3:85:cf:09:72client-name HP-Ellitedefault-router 10.10.11.1exit
ip dhcp pool host VAIO-Zaddress 10.10.14.108 255.255.255.0 hardware-address 54:53:ed:1c:a1:46

My university provides one Ethernet port per student in dorm rooms. They assign IP addresses based on which port you connect to and forbid multiple computers connected to the one port using a hub or switch.DHCP leases are 24 hours long, but you can switch out 10 different devices with different MAC addresses and keep getting the same IP. How does this work? Do they just figure that if you're using a hub connecting multiple stations to the one port that they don't care if there's a conflict?

I currently have a the following configuration and am unable to get more than 2 DHCP addresses for the devices connected to the Cisco new SG 100-16 Switch.The AP have no trouble handing out DHCP to the wireless clients, but we are unable to get the SG 100-16 to be able to do the same thing to wired clients. It is currently connected to the 2960-8 in port 1. We can get 2 devices connected without a problem, but the 3rd machine and beyond do not work. Also, setting up a static IP does not work. Using a static will not even allow us to ping or tracer back to any devices beyond the SG 100-16.

There is nice c2900PortNumberOfLearnedAddresses table in C2900-MIB, but it's outdated and not supported by modern switches.Is there similar table for modern switches? Most interested in Catalyst 2960 and 3750.

We want to permit certain mac addresses on the cat 4506 switch wherein only those mac addresses will get access to network.
Configuration Planned: For testing purpose we have created mac access list on cat 4506 and deny laptop mac address in this access list. The mac access group is applied to the port where the laptop is connected to cat 4506.Even after applying the mac access group on the port, the laptop is able to ping the vlan ip of cat 4506 [code]
laptop with ip address 192.168.10.2/24 connected to port 2/1 is able to ping 192.168.10.1 even after applying the mac access-group
Note-we have tested same configuration on cat 3560 and its working fine. We apply the mac access-group command on interface and clear the arp-cache and we are not able to ping vlan interface ip. The moment we remove the mac access-group,ping starts again.

I am trying to setup my 3550 layer 3 switch to do hand out dhcp addresses for different vlans. It is connected to my router address 192.168.1.1. I setup a new vlan 3 and the dhcp pool.. The client gets a 192.168.3.2 address but am not able to ping the router and other clients and get out to the internet.
Here is the config that I have. I deleted the other ports because I am not using them. The vlan 3 client is on port fast Ethernet 0/17 and the router is connected to the fastethernet 0/1.
version 12.2
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption

In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.

I have routing enabled, can build a static route, and go back and see it (sh ip route), but I don't know how to get the route right. I have one host (Host A) on Vlan 20 w/192.168.20.2/24 dg 192.168.20.11 (the vlan ip) and (Host B) on Vlan 30 w/192.168.30.2/24 dg 192.168.30.11 (the vlan ip). I can't ping them from any host man. I can ping the Vlans but not the host.

i wonder if i can make a backup static route for an existing link over wan using the below diagram
the Core Switch type is 3750 in both sides i`m using only static routing for all destination like
Core1:
ip route 192.168.8.0 255.255.255.0 172.10.10.30
Core2:
ip route 172.17.200.0 255.255.255.0 192.168.100.105
requirements is to track the reachibility for the core ip address from both sides & change the routing automatically to the backup tunnel line

Two Cisco C2960G Switches connected with each other using an EtherChannel Trunk Ports.IOS Image has been upgraded to c2960-lanbasek9-mz. 122- 58.SE2.bin.The global command "sdm prefer lanbase-routing" has been executed to set the default template to "lanbase-routing".The global command "ip routing" has been executed to enable the ip routing.An IP route has been configured in each switch to point to each other for the static routing purpose (Please see the 2 attached configuration files) The hosts in VLAN 111 and VLAN 110 are not able to see each other even the ip static routes have been configured.May be I have misconfigured some settings but not sure what's the actual problem.

2. Via the Networking > LAN (Local Network) > DHCP Lease Clients I can thick a Lease and click on Make Static IP. The result is an error: Operation failed.

Our company is a small one and steadily growing towards mid size. We currently have about 200 or so users. Naturally we have run out of IP addresses and now we must redesign the entire IP schema.Initially our plan was to just implement a class B subnet for the whole network with certain ranges belonging to certain kinds of devices/machines/servers.Are there any cons to this? If so, could you link me to documentation that explains this?

I have a DIR-615 rev C1 with the latest firmware (v3.13). I am trying to reserve all the IP addresses in my home network, which includes a printer, 3 computers, a network bridge to a PS3, the PS3 itself, an iPhone, and an A/V receiver. On my network setup page, I can see the MAC addresses under DHCP CLIENTS for the wired Win7 computer, a Win7 computer with a USB adapter, the PS3, the network bridge to the PS3, the iPhone.

I'm planning to setup a network with more than 300 PCs. I know that using class C address is not enough to allocate number of IP addresses required. What I meant in the preceding sentence is that If I use this network address 192.168.1.0 (class C), it will allow only 256-2 = 254 IP addresses, What about other PCs in the network ?

We got a bunch of port-sec violations on port fa1/0/42. after checking logs, we noticed that the MAC address responsible for generating the alert was not one, but many.We asked the user, he said he only restarted his computer.The MAC addresses happen to be existing MAC on the network.How is it possible that a port-sec violation is made by many MAC addresses on the same port, successively?
