Cisco WAN :: 1921 With Static IP Won't Access Internet
Feb 24, 2012
I have the same 1921 router that I am trying to install at a facility with a Static IP address and Static DNS information to get on the internet and I cannot get the 1921 to access the internet!
Here is my config:

I have been playing around with a 1921/K9 router in our dev environment. It's been about 24 hours and I just can't seem to get it to work. My DHCP Server is working hence my internal network is getting IP address as desired. But Router doesn't seem to connect to internet for some reason.
I am trying to make it a internet facing router with static IP address (67.210.209.113). LAN side of this router will be our .11 Network which is our Dev Network.
Here is some network information:
WAN:
Interface IP: 67.210.111.111
Default Gateway: 67.210.111.222 (I can ping this address through router)
tlm1921A-11A#ping 67.210.111.222

I am running a 1921 with 15.0(1)M4 on it. The router has a /29 public block assigned to it so I have a public IP for my router's GW, a public IP for the WAN interface on the router, a public IP for PAT and the three remaining public IPs I use them as static NATs for internal hosts.
My problem is that the particular static NAT assigned to static host1 seems to "hang" every few days. You can ping the public IP and it will respond but the rest of the services of the host like www, ftp and telnet do not respond. If I reboot the router then all services of host1 will work again. Note that all other static IPs including the ones used for static host2, host3 and PAT will always work and never give any problems.
I am fairly certain that this is not a config problem so I have shuffled around the public-to-private NAT entries. Basically whatever public IP I assign to this host1 will at some point hang. The host2, host3 and PAT always work and never hang no matter what public IP I issue to them.
So since it isn't a problem with the public IP I changed the private IP of host1 and still it hung!! This host1 happens to be a linux box. host2 and host3 are a Windows server and a different flavor linux if that make some kind of difference.

we use the Cisco VPN-Client to connect to our CISCO1921 Router and want to go out again on the same interface to the internet. We configured the connection with the IOS scurity package, have no split tunneling - so the client is forced with it's default gateway to our router - we also have pushed our local dns-server to the client and he gets dns results. Now I think we have to got out with some kind of NAT, because our client has a private IP from the IPSec Client pool. At the moment we have no NAT inside/outside, bacause we only use official IP addres in- and ouside (data-room usage).
- Is it possible to get the NAT function going in and out on the same interface with crypto_map IPSec user comming in and going out to the internet ?
- Is it more secure to configure this with vrf ?
- Has some a link to example configurations for this ?

I've been trying to set up my new Cisco 1921 Router to provide internet access to my local network but with no success. I've been reading guides and looking at videos and I have to be missing something becaouse I can't access internet (ping/tracert) from my local network.
The DHCP server works fine and the clients on my local network gets ip-adresses from the router but can't ping or tracert outside the local network.

I have a couple a questions answers on which i cant google for a period. BTW maybe i simly use wrong aproach to choose keywords.
1) Is it possible to assign same ip address to the same client each time it authenticated, preferably without using DHCP? Im definely sure that it possible but cant find corresponded configuration examples (my device is Cisco 1921 with IOS 15.0.1).
2) Is it possible to assign dynamic crypto map to loopback interface (the purpose to make EASY VPN Server accessible through two interfaces - maybe you recommend other approach instead?) - as i move workingcrypto map from phy int to loopback - i cant connect with reason "Phace1 SA policy proposal not accepted"

I have an RVS 4000. I have several PC's to which I have assigned static IP addresses. I have recently upgraded most of the PC's to Win 7 (64) machines. I updated the firmware on the RVS4000 to 1.3.3.5 in conjunction with this. After such update (and actually before as well) I could not assign a static IP address to a PC and have access to the internet. It connects fine to my LAN, just no internet access. This is also affected on several other machines running Win XP and Win 2003 Server, so it's not just this computer.
I have:
1. Shut down (powered off/unplugged) everything, router, DSL modem, switches, server, etc.
2. As I said firmware is current.
3. Yes, DNS servers and gateway, subnet, etc. are all correctly specified on the PC.
4. Router is set for gateway mode.
5. Set to only IPV4.
The only way it allows internet access is to use DHCP. I've even tried taking the IP address via DHCP and manually assigning the DNS servers and that works fine, but as soon as I assign a static IP internet access is immediately gone.
There must be something I'm missing, but I can't seem to find it.
Everything worked fine prior to the conversion of the Win 7 machines, i.e. I had several PC's with static IP's and no problems.

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.

We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now

Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?

I have to open several ports from the WAN to LAN on a 1921:
For example:
Say I need port 41795 both UDP and TCP to go from the WAN to the LAN, can some provide me the context I have to follow?
Currently I have this in place
Another piece of this is that the devices that will need to be accessed remotely are on VLAN10 - will that cause a problem?
is installed at a clients home for a very complex Crestron network that included 5 Cisco POE GB switches, 2 VLANS, with VLAN10 utilizing QOS and is the AV network (VLAN1 is the computer network), 8 1142 WAP's, and this 1921.

I have VPDN running on our Cisco 1921 router running 15.2(1)T. Previously I was using Cisco 2801 router running 12.4(24)T4. I copied the config from the 2801 to the new 1921 router before replacing the router but now the VPDN isn't working.
Basically the users can connect and authenticate to the VPDN, but once they get the IP 192.168.12.10-20 IP, they can't access the internal servers (i.e. 192.168.12.120).
Is there any bug in the 15.2(1)T relating to VPDN?
Here's the VPDN section of the config:

I am setting up a new 1921 for a public library and I am running into a problem and I bet I am missing something simple. All the internal stuff works and I can ping the outside IP on the 1921 but can't go any further to the internet. The 1921 has the 2 gig ethernet ports, 0/0 is connected to a DSL getting DHCP settings fine from the DSL modem. The other gig ethernet port 0/1 is running the inside network and its function fine, I have a server on it and other clients and they can ping and get dhcp settings etc.I've pasted the config output below and IP addresses of the main actors.

I am testing a EasyVPN IPsec server set up on a cisco 891. Here is how I have it set up right now- the 891 is connected to our backup internet connection (different ISP from our main line) and we have a cisco 1921 as our production router.
I am experiencing a problem where when I am on our internal network off the 1921 and I connect to the VPN on the 891 I lose all local network connectivity. Nothing works, can't ping, can't telnet to the 1921, can't browse the internet, its not just DNS either.
I believe the issue lies in the configuration of the IPSec server on the 891 because when I connect to our client's cisco IPSec VPN I experience full local connectivity with no issues whatsoever. It seems to me that ALL traffic is being routed through the tunnel.
Other than the local issues the VPN is working fine and I can remote desktop to the PC I have set up off the 891 and telnet to the 891 from there.

I have the following config using a Cisco 1921. I am trying to get devices on the the native VLAN to get internet access via the gateway x.x.x.73.Any thing being routed from the other Vlans 15/20/30 can get access, but nothing from an internal IP address. Is there something I am missing.
The Xs replace the same 3 octets for each interface.I am trying to route from VLANs 15/20/30 to see VLAN 5. I have tried a few things, in terms of adding extra ip routes, but can't get anything to work. Each of those Vlans have another router on the other side of them, which I have also tried adding ip routes too, but nothing. One of the routers (Vlan15 is a Draytek 2830). [code]

I am having a problem getting this to work and I have always done it with 2 Static ip address. but now this company changed to 1 and I am doing something wrong.
I have comcast with 1 static IP, I have a local LAN with 6 host and 1 server that does Mail and remote access and web traffic.
I need a config that allows me to use 1 static ip on the outside interface of the PIX and allow with an ACL 7 ports open to the server and allow all the local host out to the internet.

I cannot remember what I set-up as the static IP for a netgear access point so that I can access it to change a password. Is there a way to figure that out without resetting the access point or typing in every possibility in the browser?It is acting only as an access point and therefore IPCONFIG shows the main router handing out DHCP.

I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
4 Sep 20 2011 16:20:33 fw_outside_ip 62678 outside_host 2001 Deny tcp src outside:outside_host_ip/62678 dst inside_host:inside_host_ip/2001 by access-group "outside_access_in" [0x0, 0x0]
When I try to use the packet tracer to simulate the outside traffic, I get the following
5 Sep 20 2011 16:17:41 inside_host 2001 Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:outside_host/1065 dst inside_int:inside_host/2001 denied due to NAT reverse path failure
I've got over my NAT statement and access rule and can't find anything wrong with either.
Here are the pertinent NAT and access rule...
static (inside_int,outside) tcp interface 2001 inside_host 2001 netmask 255.255.255.255
access-list outside_access_in extended permit tcp host outside_host host inside_host eq 2001

I have configured the ASA in a very similar manner to how the PIX was set up but I'm having trouble with some hosts on the inside accessing the Internet. Any inside hosts which use DHCP work fine. Any inside hosts with a static IP (and configured on the ASA with a "static" rule) cannot access the Internet. For example, in the config below the server daviker-dialler cannot access the Internet. I've spent a few days working on this now and have started from scratch several times but I'm not getting anywhere. Apologies for all the X's everywhere, didn't like to post anything sensitive on the Internet.

I have a RV120W used to provide VPN access to several industrial devices. Some of these devices are assigned IP address via DHCP in the router. One cannot do DHCP, so it has a self-determined static IP.
The VPN works well for all the devices that are assigned IP's. However, it does not allow me to connect to the device that has a static IP. I can connect to it fine when I am on the LAN or WLAN, but cannot ping it via the VPN.

At first I use ACS 4.2 to create static ip address user for remote access VPN,It's easy,just configuration it at user set>Client IP Address Assignment>Assign static IP address,but when I use ACS 5.2 I can't find it.I try to add IPv4 address attribute to user by read "ACS 5.2 user guide" ,it says this: [code] I do this,but it's not work.When I use EasyVPN client to connect ASA 5520,user could through authentication but will not get that static IP address which I configuration on Internal Users.so,what should I do,if anyboby knows how to use ACS 5.2 to create a static ip address user for remote access VPN.

I running site-to-site IPsec VPN in Cisco 2811 IOS 12.4 both site. Here I encounter a problem to access server on Site A from Site B
Site A having Leased Line connected to router with Public IP. I have done static mapping 1 web server to Public IP (NAT). This to allow external users to access the server via Public IP. At the same time, users at Site B would need to access to same server via Internal IP since they have Site-to-Site VPN established. But once I done Static Mapping (NAT), user at Site B unable to access the server at Site A using its internal IP. But external user can access server via Public IP. What went wrong here. Do i need to add extra command to get this done?

I have five (5) sites all connected via static VPN tunnels. They are all using Cisco ASA 5510s running 8.4(4)1. Any internal IP on each site can ping any IP on a remote site, because of the static VPN tunnels. I have the external IP (routeable) addresses connecting to each other.
Site A: 10.1.0.0 /24
Site B: 10.2.0.0 /24
Site C: 10.3.0.0 /24
Site D: 10.5.0.0 /24
Site E: 10.10.0.0 /20
I have remote users who connect using Cisco AnyConnect 3.1 to Site E. They get a static IP within the 10.10.100.0 /24 subnet (vpnpool00) and can access anything in the 10.10.0.0 /20 subnet. So far, so good.No management wants users to access devices within the other sites, specifically Site A using teh same AnyConnect connection. In other words, they get an Ip address of say, 10.10.100.5 and now need to access a server on Site A's subnet or 10.1.0.5.I have checked my NAT statements and they appear to allow this, but so far when I do a ping I get the following: Routing failed to locate next hop for ICMP from outside: 10.10.100.5/1 to inside: 10.1.0.5/0 What am I missing? Is there a NAT statement that is wrong, or an access-list statement or possibly a static route?
