Cisco Routers :: VPN Between SRP 512W And ISR 1811
Feb 28, 2012
I have some problems with making stable VPN between SRP512W and ISR1811.Configuration:
- IKE policy - 3DES/SHA1 group2(1024bits)
- crypto map on ISR1811
One of the main issues I've noted appears when SRP loose it's IP connectivity to remote router, even if this connectivity interruption lasts for only couple of seconds. When the IP connectivity is restored SRP is unable to re-establish the IPSec session. There is connect/disconnect option in SRP menu (Status -> VPN Status -> Connect/Disconnect) and automatic VPN disable (VPN -> Site-to-Site VPN -> IKE policy -> Enable Dead Peer Detection) yet I couldn't found any option for nor automatic mechanism for VPN reconnection when the IP connectivity is reestablished. This issue lead to interruption of Site-to-Site VPN service when there is some short outages within the ISP network.
Another issue is building GRE tunnels between the same devices. Can you verify my configuration? Belive it or not - I spent more than 4-5 hours and couldn't do it.Should I make some additional settings/configurations ?
Basically, he has an office he's supporting on a contract basis, they have a cable modem uplink. They move very large (100MB or so) EXCEL files to/from a server "somewhere out there"...The place has 19 users on cable modem (presumably commercial level). They're having "severe latency due to all the users". They're also using VOIP (not sure what product, shouldn't really matter)this doesn't pass the sniff test to me- I have 70+ users on 4 T1s and don't have the problems they claim to be having. Suspect they should be doing some packet sniffing to see who's camping on Youtube, but this is not an option....They're adding in a second cable modem line and want to bind both together. I immediately figured they should do QOS, dedicate the mission-critical traffic to 1 line and let it bleed over onto the other and take precedence if necessary. They have a Cisco 1811 router. I haven't messed with those before, but what I am seeing is they are a "fixed-configuration router". Obviously there has to be SOME config changeable- if for nothing other than IP assignment to interface and such. So what does Cisco mean by "fixed-config"? Is this basically a dumbed-down Linksys router?
I need some help in configuration of Cisco IOS VPN. Basically, we have 2 Cisco 1811 routers in our company. Router 1 - Production router (IP 192.168.x.254)Router 2 - VPN router (IP 192.168.x.251). All machines/servers inside our network has been configured with a default gateway of 192.168.x.254. Hence, all internet traffic will go through the production router.
Now, we want to deploy a new router (i.e. Router 2) which will be solely used for VPN purpose (such as DMVPN, IPsec site to site, VPN client configuration etc). I have configured Router 2 with Cisco VPN client and can connect to this using VPN client application from my home PC. However, once I connect to it, I am not able to ping anything inside this network other than Router 2 IP (192.168.x.251).
Is there anything else that I would need to put into the configuration so that I can ping everything inside the network?
i have cisco router 1811 , i make port forwarding for my mail server , so from outside i can access to the mail server via my mobile but inside lan i cannot because i use my global ip address at my mobile config .
i have two branch offices A & B both connected by a vpn. i am planning to add another isp on both the locations and have it just for the vpn. i.e have the second isp do just vpn and all other traffic go through the older ISP.. what are my options ? am not planning to add any extra hardware and also am not planning on acheiving any fail-over or load-balancing because i know ASA 5510 does not do load-balancing.
I got a new 1811 series router. Its sh version output is " flash:c181x-advipservicesk9-mz.124-11.XW6.bin". I need to upgrade to the latest IOS. How can i find a latest one? How can i upgrade to the latest one?
I am a new owner of a Cisco 1811, brand new. So im trying to follow this,
[URL]...
But when i get to this,
it won't continue, if i cancel this and not setup the WAN connection then log back into after it's rebooted i can see both lan's * both disabled * when i enable 0 it wont allow me to click add or do anything else to setup the WAN connection
I am setting up my 2nd 1811 router for NAT and VPN. The 1st 1811 works great, completed a few months ago. On this 2nd 1811, I decided to just copy the working startup-config from the good, 1st router to this 2nd, and then change IPs and from there. I did not do the setup wizard, but just erased the startup-config, reloaded, gave temp IP on local LAN and copied good startup-config from TFTP server.
Question: on this 2nd 1811, I show this:
mmi polling-interval 60 no mmi auto-configure no mmi pvc mmi snmp-timeout 180 no ip subnet-zero
I do not have this on the 1st, and I cannot get rid of it. Is this due to IOS versions?
I am having an issue where the GRE tunnels are up/up but are not pingable. The GRE tunnels are on a cisco 1811 and cisco 2811 routers The tunnel source and destination IP addresses are private addresses. These private addresses are pingable to each other and they are connected via IPSEC. The IPSEC tunnels are generated from the ASA to which the cisco routers connect. Probably the tunnels are up/up because keepalives are not configured. But I am still not able to see why I cnt ping the end points. The ACL for IPSEC in ASA includes the "permit gre host <Private IP 1> hist <Private IP 2>" commands.
I have a cisco router 1811 when powered displays the output below then it hangs at that point.

Last night I had a crack at setting up PBR on my companies Cisco 1811.Joy, I thought, it's actually working. Alas I was wrong, the addresses were getting translated to our ADSLs external ip address but routed over our EFM.What I want to acheive is to send all HTTP(s) traffic from our workstations over the ADSL (FastEthernet1) whilst all other traffic and VPN goes out over our Bonded ADSL (FastEthernet0). There is also a minor failover in place for traffic routed to the ADSL in the route-map PBR_VLAN1. The servers are on IPs 200, 202, 204 and 240.
Anyway, I have re-written the configuration and xxx'd and x.a/b/c'd all the IP addresses I want to keep secret. Need to make sure that the PBR is correct, and will do what I want it to? I have a very small time-frame to get this correct and I dont want to fudge the bucket so to speak.
trying to upgrade an 1811 to the latest firmware. [code] just seems to always boot back to the original file and not the one i just tftp'd up. could it be that this router requires additional ram to support this ios?
This is problably a stupid question but how do I open a prot on a cisco 1811? I have a cisco 1811 and a computer that has VNC installed on it. I want to be able to access that computer from out side the network using the external ip address and port 5950. People outside the network will be able to open vnc viewer and type in *external ip address*:5950 and it will be directed to the computer with a static internal ip address of 10.11.101.10. What commands do I use to do this?
I have an 1811 with 2 WAN connections, Fiber and ADSL (both Ethernet). I'm having a heck of a time getting traffic out the ADSL link.As it stands, I can ping the next hop 75.158.58.1, but no further. ping source FastEthernet1 times out to any external address nor can I NAT internal subnets out the interface.I'm really at a loss as to why, especially since I can ping

I have an (old) 1811 router acting as the Internet gateway. My users like to use download managers such as Orbit JDownloader to download large files that should not download. Is there a way to block it? The download managers often start multiple connections and seem to open/cose connections.
trying to fetch the equivalent of the mac-address-table on a 1811 with SNMP. I want a mapping between active MACs to a port ifIndex (not a VLAN interface ifIndex).
- I've snmpwalked every MIBs on this device (including all the proprietary MIBs supported by the IOS)
- I've upgraded to latest IOS from the 12.4(24)T series and also tried latest from 12.4(15)T series
- I am aware of the community index (@ sign in read-only community to split per vlan)
- I've exhausted all my google skills
On 29xx, 35xx, we obtain that information using the BRIDGE-MIB, community indexing and the following OID:
I've got an 1811 router running 15.4 IOS and a cable modem with 5 static IP's attached to Fa0. I would like to dedicate one of those IP's to a dedicated internal subnet (10.0.30.0/24) but I am not sure how to accomplish this?
What would be the best method to accomplish this? Unsure of where to begin..
I’m having serious issues getting Tandberg H.323 working behind this router with NAT.
My setup is Cisco 1811 configured with Fas0 to pull DHCP (public address). This router is being used in a mobile medical clinic VAN so the setup needs to be seamless and transparent to the users. The idea with the DHCP is anywhere they go they could pull a DHCP address and then NAT behind that address. The van visits mostly small schools in the Texas Rio Grande Valley providing medical assistance and consulting to the local community. The router has an 8 port built in switch and all ports are sitting in default VLAN 1.
Basic stripped down config, only relevant commands listed…
ip dhcp excluded-address 10.0.0.1 10.0.0.4
ip dhcp pool VANnet network 10.0.0.0 255.255.255.240 default-router 10.0.0.1 dns-server 10.0.0.1(code)
Now initially I can’t even get the call to connect with just using the ports above, which I should. Also knowing there are several issues with H.323 and NAT I went ahead and added all know ports Tandberg says they use…
Basically I created static NAT entries for all the ports and the ranges above. For the ranges I had to add a line for every port.
This didn’t and hasn’t worked yet even with some additional tweaking… Finally the question… am I going about this all wrong? Is there an arrangement of commands that will even work? How can I accomplish the port forwarding setup on a Linksys/Netgear router on a real Cisco router?
I've got a Cisco 1811 router with FastEthernet0 plugged into a cable modem with 5 static IP's. I want to disable the ability for those IP's to be pinged externally except for certain addresses that I specify (I have some offsite servers that I use to monitor the ISP link for example). I also want the ability to be able to ping external addresses from the router as well as any of my inside subnets. [code]
I've tried varying ACL's and applied to Fa0, none of which work [code]
I successfully pulled it out of the box and already broke it.
What I did to lose my connectivity to it (via IP, console is OK), but I'd like to start from scratch and during my learning/experimentation I will undoubtedly need to do this over and over until I get things right.
I've found various guides, none of which look like what I am after. Basically, I want to return this to the condition that it was in when it came out of the box. IOS is version 12.4(6)T11 .
On interface FA0 goes the UTP from my ISP. Further more I have setup my Vlan1 but i can't connect to the Internet.

I want to configure my Cisco 1811 router for 1 Internet link, The router is already connected to my main site via site to site vpn . Voice + VPN + Internet traffic is going through only 1 WAN interface,
I want to dedicate 512 kbps for VPN and voice traffic. I want to dedicate 512 kbps for Internet traffic.
I've configured SSL VPN on an 1811 router running 12.4(9) IOS. I'm using the full SSL VPN client and do not want to split tunnel the traffic. I can reach my inside resources just fine, but I can not reach sites on the Internet. I want to tunnel my Internet traffic to the router and then have it hairpin out the same interface.
I've successfully configured this type of hairpinning on an ASA for SSL VPN, but have yet to find a way to do it in IOS.
I was recently tasked with adding a redundant internet connection for one of our remote sites. this new connection was to be used as the primary connection for the VPN from the site with the existing one being configured as a failover controlled by an IP SLA tracker on the new interface.
The existing connection uses a PPPoE connection configured under Dialer1 associated with FE0 to connect to our ASA. Duplicating this wasn't an option given the hardware that the second ISP provided. They provided a /29 for use; I configured FE2 using a Vlan interface with a host on that subnet.
I duplicated the connection profiles and tunnel groups on our ASA, changing only the Peer IP. Both interfaces on the 1811 are using the same crypto map.
The new connection seems fine and I can reach other hosts on its subnet from both the router and hosts on the inside of the NAT.
The issue happens when I change the default route to use the new connection.
I'm able to reach internet hosts using the new connection and I can see the VPN being established on the ASA while the VPN from the old connection drops, but I can't get traffic to route over the tunnel.
If I remove the default route that uses the new connection the VPN comes back up on the old connection just fine. There's no problem routing over the VPN when it uses that connection, just the new one.

I've heard that you can configure an 1811 router as a terminal server for remote console work.I have several of them in the lab and would love to try it out.
I have a Cisco 1811 router running the 15.1(3)T IOS. I am having some difficulty with the current zone based firewall and the SSL VPN.
When a user connects, they are put into Virtual-Template 1 which has a zone based assignment of "sslvpn". However the traffic report for the users is listed as being blocked by the zone based firewall in the outbound direction(office out to the wan zone).
I am working to test the PPPoE solution. The requirement is that she like to have a PPPoE server (7200), enable the DHCP pool on the router. The PPPoE client (1811) should receive the IP address through the DHCP and with subnet mask (/24) so that routing protocol can enable between the PPPoE server and client.We test with some initial configuration but not success to obtain DHCP address from the pool.
On PPPoE server router, ! ip dhcp pool DHCP-PPP network 192.168.254.0 255.255.255.0 default-router 192.168.254.254 [Code]...
I am attempting to install a third party SSL cert (GoDaddy) to properly secure the external interface of my 1811 ISR so that I can implement SSL VPN. I have tried using SDM 2.5, but that doesn't appear to be working. I am familiar with doing this on a Cisco 3005 Concentrator, but I'm not aware of how to install an intermediate cert on the 1811 (or if it's even possible), in order to properly have the GoDaddy cert properly imported and used for SSL VPN. I have gone through the CSR process and have the initial cert from them generated and have imported it, but it never appears to be identified correctly if I browse to the external interface on the router. The router always defaults to its self-signed cert.
I seem to be having an issue where certain very packets are being dropped/lost by my office router. The reproducible situation is, when I attempt a DNS zone transfer from my linux bind DNS server (A.A.A.A) to any server on my network behind NAT (Y.Y.Y.Y) the first packet (Seq 1) of the response is lost. The client making the query asks for first packet (Seq 1) to be resent, and the DNS server attempts to resend it repeatedly, but those are lost too.

I seem to be unable to access any IKEv2 features. The command crypto ikev2 is not available. Everything I've read suggests IKEv2 is available in this IOS version.Is there something I'm missing?
