Cisco WAN :: 881 Unable To NAT To Web Server
Jun 20, 2011
Apparently the problem seems simple enough however I couldn't get it working. My router is being configured to access a web server in the network which is on port 80. However, port 80 is being used by my router's setup page. Therefore whenever I key in my public IP address, it will just immediately direct me to the router's page.I have also tried opening up other ports like 5050 and set my web server to port 5050. Internally within the LAN itself everyone can access the web server with port 5050. However, going from public IP address with port 5050 doesn't work.

I purchased the EA6500 a few days ago, and when I'm connected to Cisco Connect Cloud I am unable to select Folder Access / FTP Server / Media Server. I click them and nothing happens.Also, the Cisco light on the router keeps blinking.

I'm running LMS 3.1 with CM 5.1.0 on a single Solaris 9 server. I've been unable to open topology services. I get an error "cannot connect to ANI server". I've confirmed that the ANIServer6.0 is running (it says "Running with busy flag set"). I've also tried restarting the Daemon Manager. What should I look at? Could it be a Java problem?

I am trying to get my ACL's to work, but when ever I do an extened acl and let certain one in (80,443,21,etc) my computer gets an internet error saying it cannot conntact the dns server. I've tried severl ways to fix it, but cannot seem to get it to work.
Right now i just have access-list 1 on. Eventually I would like to have only "Apple" and 101 on.

I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues. For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.

I've been trying to open ports to start a server on some games that I play.I used a guide that shows you how to set up the server and open up the port, but I can't get it to work.I've tried making an exception in my firewall,but that didn't work, so I tried completely disabling my firewalls. Nothing. I've gone into my router settings and opening a port this way: But it still doesn't open it up. This is what I'm using to check it.In fact, NONE of the ports are open it seems? No matter what port I try to type in on the port checker, it always gives me that same error.

My laptop is connected to a router via wifi but it keeps getting a DNS fault. I have another PC linked to the same router via WiFi and that works perfectly all the time. I have the same problem on both google chrome and IE browsers where I just get the message telling me that the DNS look up failed. My internet is still connected as I can dial into my remote CCTV cameras and I can ping website ip addresses. Most times I can just turn off my wireless adapter and turn it back on and it works for another hour or so. But sometimes it wont work all day, unless I start my laptop in safe mode, when it works everytime! I have flushed the DNS cache several times but to no avail.

I have a server with two adapters: 192.168.1.200 and 10.99.1.200, 10.99.1.200 connects to a cisco router 10.99.1.254 (which I have no access to). This connects via WAN to another network to transfer files to another company. 192.168.1.200 is connected to our local LAN. I have a service that uses FTP to get and send files to a server through 10.99.1.200. I recently had to switch our IP scheme from 10.99 to 192.168 and since then haven't been able to send files to the ftp server. My question is, would a router solve my problem? If so, would I; remove the 10.99 adapter, connect 192.168 to the router, connect the router to the switch, connect the 10.99 gateway to the new router (and update any appropriate routing tables on the server)? The service appears to have issues with using a dual homed server and updating it isn't going to happen anytime soon.

They came and installed a router and disconnected my old one. I then connected my new ISP router to my switch and now Im just stuck. At one point I was able to connect to my drives but was unable to connect to the internet. But once I call the ISP they had me change setting for Ipv4 changed defualt gateway, Ip address and DNS after that I was unable to reconnect to my drives. I've done full shut downs and restarts and nothing has worked. 1 of the computers connects to the server through wifi. I also run a VPN.

I have 2 routers, one is an Apple AirPort Extreme with a static outside IP address, I also have a Cisco 871 with a static outside IP address. The Airport Extreme connects to a switch on the private network and has an IP address ending in .1. The Cisco 871 connects to the same Private network and it ends in .2. The 871 is setup as a VPN Server. now when clients connect to the VPN they can ping the VLan IP Address on the 871, but they can t ping any other hosts on the smae network. The hosts on the private network can ping the vlan on the 871.

configure Cisco Ace 4710 ?Note :- Just a testing face I need to access my one server(192.168.1.11 : 80) through VIP :- 10.13.77.10 , I have only one Cisco Router 2800 and One L2 Cisco Switch 2960 and Cisco Ace 4710 . So I already configured 2 Different VLANS in Switch (Vlan 10 & Vlan 100) and by router I given the ip address of that Vlans with Inter Routing Vlan. My Connectivity is like this :-- Router Ethernet 0/0 --- 10.13.77.1/24 with vlan 10) & Router Ethernet 0/1 ---- 192.168.1.1/24 with vlan 100 ) connected with switch after that I configured ACE LB and connect the ACE interface with switch Like that ---- Connect to ACE Interface 2/3 vlan10 with switch vlan10(Ethernet port 2-12) and Connect to ACE Interface 3/3 vlan100 with switch vlan100(Ethernet port 13-24) .Testing to access server from Switch Vlan10 to Vlan 100 where my server is there.
Configuration :---
ACE> client side Vlan10 (10.13.77.4/24) , VIP :- 10.13.77.10, SM-- 255.255.255.255
ACE> server side Vlan100 (192.168.1.5/24), Web server -- 192.168.1.11 with 80 port
ACE> Managment Vlan 1000 (172.16.6.5/24) ,
ip route 0.0.0.0 0.0.0.0 10.13.77.1
I already Configured in Routed mode but From Vlan10 ip subnet example like 10.13.77.12(Client or User PC) tried to access server 192.168.1.11 with VIP http://10.13.77.10 but not responding , if i access server with real IP then accessible (why boz there is inter vlan routing)?

I am using the Cisco VPN Client 5.0.06.0160 - and am having an issue connecting to my ASA 5510 via VPN. This issue is happening on 1 of our laptops. All other laptops connect just fine. So the problem is not in the ASA. I have double checked the client setup and config and it too is correct. The interesting thing is, we are connecting to an IP Address and not a host name.

I am having linking a computer to our SBS server. The computer in question is set in a warehouse on our site. We have a leased internet connection which is used on a number of different offices. The sbs-server has an IP address of 192.168.50.254 with a gateway Ip address of 192.168.50.1. The firewall on this network has an external IP of 10.50.0.37 with a gateway of 10.50.0.254 and this links to the leased line equipment. The external IP address for this network is 62.7.70.237. The PC in the warehouse has an IP address of 192.168.0.2 attached via a router to the leased line. The routers Ip address is 192.168.0.1, the external IP address is 10.50.0.55 and a gateway of 10.50.0.254. This links to the leased line and seems to have an external Ip address of 62.7.70.238. My issue is that I want the PC in the warehouse to be able to connect in some way to the SBS-Server. I cannot seem to access it via the external IP or the gateway (10.50.0.37).

Lately I have been experiencing an annoying issue with my connection. My signal strength is excellent, but every 5-10 minutes I have the problem that the DNS server can't be resolved, so I can't visit any websites. All I can do is wait, the problem disappears after a few minutes. I tried ipconfig /flushdns but that didn't work.

I did nothing different to my computer. It was online fine and then an hour later when I came back, it wouldn't load any pages. I have a DSL modem and a wireless router that also connects another family member's desktop to the Internet. (As well as our phones via wifi.). The connection is fine on the other PC through a wireless adapter (both are desktops), and on the wifi the phones work perfectly so I know the modem and router aren't the problem. But even though my desktop says it's connected (not wirelessly, it directly connects to the router.), no pages will load. If I use chrome browser it eventually tells me this webpage is not available regardless of which page I try to load, or sometimes it's telling me no data received - unable to load the webpage because the server sent no data. Yet oddly a couple of times after forever it seemed to half load a couple pages. Internet Explorer just keeps trying to load pages forever with blank white page as a result.

I have been trying to connect to the Internet via a wireless connection but keep receiving the above error. None of the Windows solutions resolve the problem. On Google Chrome I see a screen saying 'This web page is not available', and receive 'Error 105: Unable to resolve the server's DNS address'. I cannot access Internet Explorer either.The strange this is that this problem only seems to occur with some wireless networks, as I can connect fine at home. In certain places, however, I am told that I am connected but that accss is 'Local Only', and I cannot open any browsers. I need the problem resolved as soon as possible as I cannot access the internet where I need it most.

I have a VPN setup thru a Cisco 5520, Windows clients connect just find and the end users configure there browser to use our internal proxy servers. Users with the MAC OS X Anyconnect client can connect, they configure their Mac to use our proxy server, but the broswers will not work, clients can reach networks and resources behind the VPN gateway and have access to the Proxy(Tried a telnet to that hostname/port). I am running ASA 8.3(2), Anyconnect(OS X) 3.1.01065.

This isn't a big deal as the rest of the ACL works fine, but this is an annoynace since the web auth redirects to our company website (internal for now) after successful login.We have a Cisco WLC that provides access to our production and guest wireless environments. The guest environment of course is in a separate vlan (10.10.50.0/24). So I created this ACL:
access-list 107 permit udp any host 10.10.2.13 eq bootpc <----internal DHCP server
access-list 107 permit udp any host 10.10.2.13 eq bootps
access-list 107 deny ip any 10.10.0.0 0.0.255.255 <---all internal networks
access-list 107 deny ip any 172.28.16.0 0.0.0.255 <----DR Network
access-list 107 permit ip any any
int vlan 50
Desc "Guest wireless network"
ip access-group 107 in
This ACL basically gives the wireless guests access to an internal DHCP server and full access to the internet. For the 10.10.50.0/24 scope, the DHCP server assigns Internet DNS servers and my rationale is that wireless clients would access it via the external IP address but I suppose it doesn't work quite like that with the website being behind the same router as the client machines.

I have an unusual issue, for which I can find nothing on the net similar.
Setup:
ASA5505 = > CISCO3524 => Windows 2012 server
ASA is internet edge with ACL / NAT implemented.
We are wanting to implement inbound NATs for this server - 3389. We have many other servers on the internal side of this ASA that we are NATing to. Creating NATs using the same outside IP to another server is fine, no issues. This other test server resides on the same VLAN as the windows 2012 server. All IPv6 is turned off on the W2012 server, and it can web-browse out via the ASA as well. No matter what I do, however I cannot get iinbound NAT, on ANY port to this server working. Internally from another server to this server on any port is fine, i.e. we can RDP to this server without issue, so we know this works - the firewall on this server is turned off too. This is our ONLY w2012 server on the internal side. When we run a wireshark on the server whilst testing the NAT there is no traffic, so its getting blocked somewhere.
The config of the ASA is fairly big to to santize it and remove all customer reference would take a while to make display of this secure difficult.
