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?
View 2 RepliesIs it possible to have more public addresses to more internal addressees? I have an internet provider which is in control of my router and he is telling me it is not possible. It's a Cisco router and I have static IP address.
View 1 Replies View RelatedIs 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 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.

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?

View 5 Replies View RelatedI 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.
Is it possible to two or more public IP Addresses bound to a Cisco ASA 5505 running 8.4(2).
View 9 Replies View RelatedI have set up a private domain network at home. I have a domain controller, a DNS server, and a DHCP server all running on one Windows 2003 Server machine. I have about 10 other machines around the house, getting their IP addresses from this DHCP server.
I have a Netgear WNDR3700 router.
I am about to get 5 public IP addresses from my ISP, and I would like to make some of these machines publicly accessible (while still accessible from the other machines in the network).
I found this link that says on my web server (one of the public machines), that I should use a second NIC and set that up to connect to my router (and get a private IP address from my DHCP server).
I have a Netgear ProSafe VPN Firewall FVX538. But I also have 10 Public IP Addresses that I will like to setup for three web services. So how do I set this up. With multiple routers. Or can my Netgear FVX538 take multiple Public IP Addresses to the same ports. If not how can setup multiple routers. one being the main one.
View 1 Replies View RelatedI 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.
View 2 Replies View RelatedI'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.
On an 887VA running 15.x IOS, is there a way to support both public and private addresses on inside vlans? The outside interface is public static ip, so the requirement would be to not nat anything if coming from inside vlan10 but nat if coming from inside vlan20.I didn't think this was possible since the outside interface would have to use an outside nat command that would not be ignored for traffic coming from vlan10.

Since then, the"home group" I set up originally with the connection wizard disappeared, and it had not been able to connect since then. When I try to connect I click on a small icon in the lower right that says, "not connected, connection available", then I click on the button to connect to broadband and get the errors described above.

View 1 Replies View RelatedI was working with Motorola SB6120 cable modem regarding an odd power cycle issue (it would power cycle randomly for 24 hours). While trying to diag the issue, I was taking a peak in his router config and found a port set to forward as:
Application: Comcast
Port From: 888
Protocol: Both
IP: 192.168.100.1
Port To: 80
I understand that his modem admin page is now available from the internet. He said his friend set this up to "modem", but I don't see any advantage of having this done. At this point what are the other advantages of forwarding such ports?Another key note: When the port forwarding was disabled, suddenly the power cycle issues stopped.
I have a Motorola surfboard sb5101. Provider is comcast.I have never had any problem with my equipment until now. Here is whats going on. I bought a used sb5101 a week ago so that I would not have to pay the rental fee anymore. Comcast activated it, and it worked fine for a week or two. The other night I got disconnected from XBOX live randomly in the middle of a game. Thought maybe just a hickup, no biggie. Well it happened 3 more times in a few hours, then again the next day.So thinking maybe this used modem is bad, I plugged back in the rental from comcast which I still had. Worked fine for a while, then the same thing, random dissconnects after 10 min, 30 min, 2 hrs into a game...etcOn both modems, the 1st and 4th green light are solid, the 2nd and 3rd green light are flashing when the connection from LIVE drops.So I'm starting to think know that neither of the modems are bad. I then try going directly to the modem instead of the router, never had any problems with the router but figured I try.I even went into the attic and got rid of the 4 way splitter that feeds cable into all the bedrooms and put in a 2 way instead hooking up only the cable line im using for xbox. Thought maybe the signal is getting degraded to bad, eventhough never had a problem before.So now I'm practically hooked up right to the line coming off the street, ethernet cord plugged directly into the modem, no router. Still dropping connections randomly with same 2nd and 3rd light flashing.The connection needs to be completely stable for multiple hours.Also, I called comcast when I had to reactivate the rental modem, so they did refreshed that modem and reactivate it, but still had the disconnects the next day.
