I have a Cisco 877 at home and need to find out what it's public IP was yesterday. I turn it off at night and usually I get the same public IP based on my ISP's lease, but can't be sure, anyway I can check this?
View 2 RepliesOne of our vendors requires using a public ip address to setup a site-to-site IPSEC vpn. We only have one public ip address and that will be used for the vpn endpoint and for internet access for the local network. I've setup policy NAT from our local network to the outside interface. I'm also using the outside ip address for the crypto map. The tunnel setups successfully and the Tx count increases anytime I try to ping the remote network, but the ping fails and the Rx count does not increase. According to our vendor, we should be able to ping the remote network and connect using port 443. When trying to connect using port 443, I see a SYN timeout in the logs. I'm not sure if the problem is on their end and they're rejecting our traffic, or if something is misconfigured on our end. I'd like to make sure that I have everything configured correctly before I go and point fingers at them.

i need to allow https traffic to a server in the DMZ that will have a routable IP address will just an ACL suffice ?which interface do i apply it to ? wan or dmz ?i dont need a NAT since the DMZ is a routable space?
this might sound straight forward, but every other pc or console can find and connect to my router.This issue seems to happen about once every few months, sometimes it comes back by itself and reconnects completely fine.
There isn't a "user limit" on our router.Wireless adapter is dell wireless 1505 draft 802.11n wlan mini-card.
Have restarted PC and uninstalled and reinstalled the card.I tried to set the i.p address to static but it says "adapter disconnected" so won't allow me to edit any settings, despite it being able to find neighbour's wireless very easily.
I'm trying to setup my DMZ so all my servers will have public IPs assigned to them. I'm currently trying to use two interfaces on each server, one with a private IP and then one with a public IP. All my internal traffic will go over the private interfaces...this is working. However, I'm having a problem trying to get it so the public interfaces work. Ultimately, these will be VM Hosts and have VM guests on them, each guest will have it's own public IP.
View 14 Replies View RelatedI am trying to configure a SSL VPN on a Cisco ASA5520. Unfortunately the port 443 of the OUTSIDE interface of ASA is already in use by Microsoft Outlook Web Access and I cannot change the configuration of Outlook. This configuration already in place prevents me to use the public IP of the ASA as Cisco VPN ip address for the webpage. I don't either want to use a different port so to keep life easy for the users.I have some public IPs available that I can use so I wanted to use one of them instead of the ASA's OUTSIDE interface.
View 7 Replies View RelatedMy ASA 5510 is configured with a single PUBLICIP1 on the outside interface. All internal hosts 192.168.0.x are behind the ASA firewall and NATed to PUBLICIP1 including a few site-to-site VPN tunnels. This is also true for DMZ. Now, I would like to add a second PUBLICIP2 to the ASA and map it to one internal host ONLY - For eg: 192.168.0.25. How can I do this without effecting the existing setup? Since my entire internal subnet 192.168.0.0/24 is NATed to an existing PUBLICIP1 how can I exclude just one host (192.168.0.25) and bond it to the PUBLICIP2 for all ports.
This is what my current OUTSIDE interface looks like.

We have a T1 connection at our office with a block of 5 IPs. The external interface is simply one RJ45 jack. Currently we have a home spec router connected to the external interface, and then a switch connected to the router. Certain ports are forwarded to our server in the home spec router for things like OWA, etc.I would like to start putting our other IPs to use. Is this usually done by having a switch connected to the external device and then have multiple routers connected to the switch? Or is it one router capable of VLAN or is it something entirely differentReally, what I want to know is what the rest of the industry typically does to use their multiple IPs.

View 1 Replies View RelatedI will be provided with /29 public IP address from my ISP. The idea is to run OSPF between ISP and my ASAs over private IPs so /29 is presented to ASA. This is because I will be using 5 out 6 available IPs on my ASA so I cannot use them on the routers.I need to run HA in Active/Standby mode on ASA, terminate site-to-site and remote access VPNs on ASA, and use static NAT for kit in DMZ network I am trying to figure out how to present this public IP range on ASA. Should I create two subinterfaces on physical interface towards OSPF area and assigned private IP address on one of them for OSPF and public IP on another and then setup a failover on each subinterface.

View 2 Replies View RelatedI've currently got my ASA (5505) serving a /28 public subnet. I've ran out of IPs, so my DC has issued me an additional /24 subnet that they have routed to my ASA. What needs to be done on my ASA so be able to use these new addresses? I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.

For a branch office we have an ASA5505 connected to the ISP with an DHCP provided public IP "locked" to the local MAC This works ok!Now - the ISP may provide up to 5 public IP's (all DHCP assigned).Is it possible to configure 2-5 public interfaces in the ASA?? As IP's are DHCP assigned there must be something (a interface) to request the address.Would this be possible, and if so - what license would be required??NAT routing on the inside should be possible as well.

View 8 Replies View RelatedI have an issue with routing public IPs on the RV042G. I have been able to route the IP's in a couple of different ways, but there is always a nagging problem.
I have a PPPoE Business Class account with 5 routable public IP's. I would like to route the IPs and manage the private network using the RV042G.
Here is what I have tried and the problem that arose: 1) I used 1:1 NAT and the servers responded with no issue. This would be a workable config however I use Kerberos for single sign-on for my clients. To use this security protocol and bind the clients to the server, I must use a public IP on the server machines. In this scenario however, everything else worked fine. 2) I then tried using the DMZ and putting the servers on the DMZ port with a public IP entered in the network config of the machine. That even worked fine and I was excited until I noticed that the servers were reporting the public IP assigned to the DMZ port as their IP when they sent mail. I then ran a test and that is the case. The servers - each with a public IP - are reporting the IP of the DMZ port. I can't have that because the mail servers need to announce a correct IP so the reverse lookup will match. Once again, a little gnat gets in the soup.
We have an asa5510 running as an SSL VPN gateway using one public IP address (e.g. 1.1.1.1) as the target IP address for the users.
Now we need to run a 2nd public IP address on the same asa5510 as target IP address for a different set of users, e.g. 2.2.2.2.
NAT is not working, secondary IP address is not possible, sub-interface is not the right way. Is this really not possible?

I have a task for a config I have not done before. I'm replacing an older 831 and PIX with a Cisco 881 router with Firewall feature set. The router receives its public IP address dynamically and there is a static public IP range also assigned with a couple of NAT statements on the PIX for a few public IP's.I'm ok with the core router config but the range is where I'm a little stuck. Current setup is as follows
Internet ---------- Router( Public intf Dynamic IP----internal intf Range IP)Router-------------PIX (outside intf Range IP---------Inside intf private net)Pix-------
As per the aboive the PIX had a public IP address from the range on the outside interface with a default route to the Router inside interface which uses a public range addres.
With my proposed config I've setup the outside interface as dynamic and just created my nat statements for the Range IP's. I believe I'm correct that I do not need to actually have a Range IP address configured on the router?
