Cisco WAN :: 2821 How To Assign For A Port One / More Public Addresses
Nov 2, 2011
I just thought if it's possible to make sure that only approved IP addresses for each of divisions of a company can be used.How can I assign for a port one/more public addresses and be sure that only this port is using it/them. Thing is I have only one 24 bit public Network ID provided to me by ISP. One IP address of the range is used for ISP's gateway. So I have 253 addresses to be distributed among divisions. However to avoid IP address conflicts I have to be sure that only dedicated for a division IP address/es is/are used by the division.
Router is 2821.
Switch is 2950.

I'm currently replacing my ASA 5505 with a 5510. I have a range of public IP addresses, one has been assigned to the outside interface by the setup wizard (e.g. 123.123.123.124 ) and another I would like to NAT to an internal server (e.g 192.168.0.3 > 123.123.123.125). On my asa 5505 this seemed fairly straigh forward, i.e. create an incoming access rule that allowed SMTP to 123.123.123.125 and then create a static nat to translate 192.168.0.3 to 123.123.123.125. Since I've tried to do the same on the 5510 traffic is not passing through so I'm assuming that the use of additional public IP addresses is not handled in the same way as the 5505? I also see that by default on the 5505, 2 VLANs are created, one for the inside and one for the outside, where as this is not the case on the 5510. Is the problem that VLANs or sub-interfaces need to be created first? I'm doing the config via ASDM.
Everything else seems to OK i.e. access to ASDM via 123.123.123.124, outbound PAT and the site-to-site VPN.

I have a customer thats got a Linksys router now, that has a DMZ port.The DMZ port is configurede to it routes the extra public ip-adress to the DMZ port it has.At the DMZ port they have another router connected, where they routes the public ip-adresses på some other devices.How can i make this setup on a Cisco ASA 5505 (With the Security Plus licens)What i have to do is to replace the Linksys router, and make it so, so it works like it was before with the Linksys.

I have a Motorola Surfboard Modem connected to a Netgear 24-port switch. I bought the WAP4410N to provide wireless connectivity from the switch.
All my PC's can get perfect connectivity via the switch but none of my wireless devices can connect at all.
Sometimes I can get 1 PC to connect but what's strange is I can view my networked folders and such but cannot access the internet.
I've upgraded the firmware to the latest May-2012. IPv4 and IPv6 are both set to automatic.

I imagine I can use the framed-ip-address attribute to assign ip-addresses but there seem to be support for static ip addresses only?A bit of a drag when we're talking 200+ nodes.

I have a peculiar situation where I need to assign a public ip to a computer without going through firewall (for testing purpose).
I have the leased line going through a 3750 switch to the ASA 5510(15.240.1.2/30) belonging to vlan 999. ASA has default route going to 15.240.1.1/30(ISP).
I have different public ip range for LAN and WAN My WAN ip is 15.240.1.0/30, LAN ip range is 15.240.2.24/27 nated by ASA..
I want to connect the PC to the switch port belonging vlan 999 and ip address of 15.240.2.26/27.
If yes, what will be the gateway for the computer?

How do i tell my firewall to start listen also on another outside ipadress assigned by my ISP? I have it used on other firewall right now. So my steps would be shutting down ip address assignment off old firewall interface. Assign that ip address to ASA5510 outside interface and configure NAT.

I have 1 2821 router with several IP addresses from a single provider. The IP addresses are not contiguous.I would like to NAT different internal subnets to different external IP's. i.e. map 10.1.1.0 to x.x.220.68 and 10.1.2.0 to x.x.220.70 and 10.1.3.0 to x.x.105.184.
I currently have ip nat inside source route-map SDM_RMAP_1 interface GigabitEthernet0/1 overload that translates everything to x.x.105.184.What would be the best way to setup the NAT statements to be able to divide up the subnets?

The 1130ag was the LAP model but I upgraded it to run in autonomous mode. My understanding is that it cannot assign IP addresses but I just want that confirmed. It is not connected to a WLC nor a server that can do DHCP.

Is it possible to assign the public IP on the WAN port to a single device on the LAN side without setting the router to bridged mode? This feature is available on Thomson modem routers but i can't seem to find this setting on the WAG120N.

I have a n150 and it only allows private ip addresses for the lan setup. Is there anyway to assign a public address? I need to have the DHCP use a public range and I can't do that unless I can set the router to a public ip.

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

I have a PIX 515E that I want to use to as a border between my internet connection and my Cisco AIR1131AG. I have configured the PIX to have the outside interface as a dhcp client which gets its dynamic IP address from the cable modem. the AP is connected to the E1 inside interface. Now I could see the E1 interface from the arp table from the AP but I cannot ping it. From the firewall I don't see the ARP table from the firewall. and i cannot ping the AP. what is wrong with the configuration? side note, i am able to connect to the AIR1131AG from my laptop I was not able to retrieve an IP address.

The router is 2821 and is setup to perform static NAT from one internal ip address mapping to one external ip address for each of our servers (inside the LAN): [code] Servers all have internal ip addresses and each of them represented to the outside world by their public ip address with above command on the router. Here is the problem.When I'm in a server (for example 192.168.0.210) and try to access other servers by their public ip addresses (i..e. *.*.*.211) the connection fails. However, When i try to access the same server by it's private IP address (i.e. 192.168.0.211) it works!
My issue is i don't want to modify windows host file for a manual mapping (for example mail.mydomian.com goes to 192.168.0.211 rather than *.*.*.211) because we host many domains and just doesn't make sense to do it one by one.So we must be able to access our servers by their public IP addresses in order for us our applications works correctly.

My ISP recently started offering dual stack IPv6. After changing IPv6 from manual tunnel to automatic, none of my devices get an IPv6 address from the ISP. In the troubleshooting page, IPv6 address is also empty. I tried resetting the router but had no difference. We have another router (ASUS RT-53N) and it works fine.The ISP is using PPPoE for IPv4. In RT-53N I choose "IPv6 with DHCP-PD" and Interface "PPP". There're no such options in EA2700 though.

I would like to configure an 877w I just bought. It's connecting to a UK ADSL2+ link.I'm a penetration tester and I want to put the Cisco router in front of my existing firewall which has an IPS on it, so that it doesn't get in the way of port scans and vulnerability scans. My ISP has issued me with 14 usable addresses a/240 subnet and basically I want to be able to use the route with just the public IP addresses. I have configured Cisco routers before, but never with this type of configuration. It's always been single public IP address NAT'd through to one or two internal LAN's.
It will be nice if I could assign the wireless and fast ethernet ports to the same VLAN using the public addresses. I don't want to use DHCP I'm quite happy statically assigning IP addresses to the computers wireless and LAN interfaces. I am reasonably certain this is possible because not sure how to do it and a little busy at the moment carrying out penetration tests.

i have Cisco 1941(with security lic) and i have been asked to make a VPN with public IP addresses so there will be no info about internal networks. Other side has ASA 5520 and they provided me with 2 public IP addresses. i have done many different VPNs but this is first with public IP addresses and i cannot figure it out.So here is the question:
1. How to do it ? (maybe some example)
2. Do i need two public IPs to do it ?

I just bought an SA520 to replace my existing FW.
The thing is that I have private IP adresses on my LAN, and I have been issued a public IP network for my DMZ by my ISP.
Meaning I want to NAT my LAN but not my DMZ, but I can't seem to find a way in the 520 to do that. I can only find the oprion to turn off NAT all together.

If there are any small business routers that offer one-to-one NAT? I have several public IP addresses assigned to me by CenturyLink. I have two servers that provide email and web hosting for two different domains. I want to put the client machines on one VLAN (VLAN Z) and assign it a public IP address (to keep server traffic separate). I want to put each server on its own VLAN (VLANs X & Y) and assign each server its own public IP address. I need the router to be able to provide a firewall and port forwarding for each VLAN. I also need to be able to route traffic between VLANs so the clients on VLAN Z can access their email and the websites on VLANs X and Y. I also need to be able to route DNS traffic between VLANs so each server can provide name resolution for their respective domains.
So, is this possible with a small business router or do I need to look at something different? I'm fairly certain this configuration is not possible with my current Cisco RVS4000. What it boils down to is I need a router that is capable of having multiple public IP addresses on the same interface and to forward those public addresses to private VLAN subnets. This would be one-to-one NAT if I understand it correctly..

I am trying to figure out how this works. I have an ISP device that connects to my 1841. ISP and fa0/0 hold the /30 WAN addresses. Fa0/1 hold one of the public IPs, lets say 1.1.1.1/29. Then the outside interface of the ASA holds 1.1.1.2/29. Now I have two routes in the 1841, one for default route going back to the ISP device, and a route for the 1.1.1.0/29 network going to the ASA.Now I have 4 more publics I can use 1.1.1.3 - 6. I do not want to assign these IPs to the servers, but yet just NAT them. I know this is possible, but cant figureI took an internal host and did a one to one static NAT from private to public. Packet tracer says my NAT rules are ok. Allowed all IP traffic for testing and still can't ping the server.

The client has a Cisco RVS4000. There are 3 Internet devices need to be accessed from the outside and will use one public IP for one device. I don't see any options to setup on Cisco RVS4000 to do 3 NATs. If Cisco RVS4000 doesn't work in this situation, which router will do?

I have this motorola sbv5121e modem. I can connect one PC to it directly. When I try to connect a secont PC, via a switch, it won't give out 2 IP addresses. Moreover, I see that the one IP address it does give out, is a public one (like 22.x.x.x). I'm on XP and show the addresses with ipconfig. Is this modem defective hardware-wise, or is some setting internally wrong? How can I see what the DHCP server does?

Is it possible to have multiple public IP addresses that are from different subnets going through one router? I have been told that this is not possible with most routers and that I would have to spend a lot of money on a router to be able to do it. I am still not totally clear on what defines a subnet even after reading up on them. What I am trying to achieve:
-My office has 10 computers.
-All would be connected to one router.
-My internet service provider has provided me with 10 public IP addresses, that are all very varied (which I asked for)

I have a customer that has an RSV4000 Router. The customer has also purchased a block of 5 usable public IP addresses. I need to be able to assign these public IP addresses to printers either by configuring a static IP on each printer directly or thru IP mapping or some other method. Does the RSV4000 support using multiple public IP addresses and if so what configuration is needed in the router for the printers to be seen by the outside world.
