I don't know much about routers, but lately I've been playing around with router configuration and getting better but I am kind of stuck now.
The scenario is this.

Cisco Infrastructure :: NATing With Router 1800

Oct 12, 2011

I have the following network connected and configured to a single Cisco 1800 router.

VLAN 2 (
int vlan2, ip address
 Cisco 1800 ----- int fa0, public ip address ---- Internet
int vlan3, ip address
VLAN 3 (
VLAN 2 is server vlan with a webserver.
VLAN 3 is clients.
NAT configuration:
VLAN 2 and VLAN 3 is using NAT to access the internet, and both is configured as inside interfaces.fa0 is configured as outside interface. Now I don't know if this is about NAT, but I've tried several things without luck.
A client in VLAN 3 tries to access a domain on the webserver in VLAN 2.It starts by sending a DNS query to a DNS server located at the ISP, and gets the ip address for the domain, which is of course a public ip address. Then nothing happens because the client tries to access the domain on the webserver using the public ip address, and the webserver have a local ip address which is on the local LAN (VLAN 2).
I've tried NAT because I have to change the destination ip address, but I can't seem to get it right.

Cisco WAN :: Limiting Bandwidth On Router 1800 Series

Jul 29, 2010

I will have this one router. Its f0/0 will be for the Internet connection with bandwidth of 30Mbps. Its f0/1 will be connected to a switch for internal networks. This link will be separated to 3 VLANs for 3 internal networks. I'm wondering if there is a way to gurantee 10Mbps for each VLAN but allow use up to 30Mbps when another two VLANs are not using any Internet bandwidth? I only worry about download bandwidth from internet.The 3 internal networks will all have public IPs and they belong to their own subnets. There won't be NAT/PAT.

Cisco WAN :: When Creating Failover Setup Cause 1800 Router To Hob Away

Mar 20, 2013

I have been given a task, where I need to create a failover setup from a 1800 Cisco router to a LAN network 2 hobs away (see topology).The reason I have been given this task is because the wireless links are not so realiably, but necessary.I'm thinking of doing this failover task with IP SLA on the routers fiber 1 and fiber 2 link, so when/if one off the links goes down, it instantly chooses the other link.I have also been thinking about implementing STP instead, and replace the router with a switch, but i'm not sure exactly how to implement it. Unfortunately I'm not able to test anything, as we are still waiting for the fiber lines, but I want to be prepared as much as possible.

Cisco WAN :: Failover On Router 1800 Having DSL And Leased Line

Feb 4, 2013

Leased line is between dammam      to dubai and the dammam office is getting internet from dubai.The ip address of Dammam      office is class A (Public IP) x.x.x.x and for dubai it is y.y.y.y which we are      using as proxy for accessing internet.I purchase the local DSL      direct line connection through cable from Local Provider and this ip address range is - it possible to use the DSL      line as failover, so if one line goes down the user should remove proxy      and can use local internet.The router which is using is      cisco 1800. 

I believe that failover is possible, 100%, but would like to know how I can do it and requesting for sharing more inputs about failover in this case.

Cisco WAN :: 1800 Router - Trunk Port L2 Switch

Feb 24, 2011

Currently I have a 4510-48g HP3COM switch as a core switch for my 4 VLAN network (which I hope to send back cause it doesn't do what I wanted it to do... PBR, which is what I need to route specific VLAN's to specific interfaces on the sonicwall,.. cause sonicwall dont understand trunk or spanning tree,. meh!) This may not happen so I've dug out an old CISCO 1800 sdsl router that has 1 FE0 port and 8 other ports, FE 1-8.
The first thing I need to do is get everything to talk to each other. So I plugged the switch into it via its configured trunk port, and configured 4 sub interfaces on the router 1800 and all seemed happy as larry and working. The problem I have is I dont seem to be able to create sub interfaces on the other ports!?

Cisco WAN :: 1800 Series Router - QoS On FastEthernet Subinterface

Jun 28, 2011

We have 2.5 Mbps connection from an ISP at our branch routers (1800 series)with single physical link terminated on FE0 but have two subinterfaces with separate subnets.
I have applied the following policy-map outbount under physical Interface FastEthernet 0. Show poliocymap output is as follows
Policy Map QoS-OUT
   Class Email
     priority 512 (kbps)
   Class SQL
     priority 512 (kbps)
   Class File-Copy
    police cir 1024000 bc 32000
      conform-action transmit
      exceed-action drop
   Class CCTV
    police cir 384000 bc 12000
      conform-action transmit
      exceed-action drop

But it seems that sometimes( not all the time ) the CCTV traffic seems to exceed the 384k and chokes the entire link(2.5 mbps).

Cisco 1800 - Router Bandwidth / QOS And Rate Limit

May 21, 2012

I apologize in advance if this is a novice inquiry, but our company just switched from Point-to-Point T1's to Metro Ethernet.

On one point-to-point, from our main office to one of our high profile locations, we had two bonded T1's. Now this site has a 3 Mbps Metro-E link, but it's being over-saturated. I don't know what type of QOS implementation our T1 provider had, but it prevented flooding. Now, I'm getting horrendous latency as the office peak hours approach since there is no QOS on the mesh by our Metro-E providers.

Ultimately, my question is: what's the best way to set a Fast Ethernet port on a Cisco 1800 series router to limit all bandwidth to 3 Mbps? At the moment, I don't have a preference in which traffic takes priority. I tried the rate-limit command, along with a speed calculator I found online, but that slowed the network down immensely.

Cisco WAN :: 1800 Updating System Image Without Rebooting Router

Feb 26, 2013

I recently formatted the flash drive of an 1800 router and replaced it with an updated image. However, the new features within the new image aren't reflected in the router. I believe that this is because a reboot would be required for the updates in the new image to be reflected in the router i.e. the image needs to be added to the system. How to get the image to the system without a reboot and if by doing so I would get all the new features from the image.For example, the show version below shows the old image in the system as [code]

Cisco WAN :: 2901 - Configure Router Overload NAT (IOS 15)

Jul 5, 2011

I am attempting to configure a Cisco 2901 router using IOS 15 to  properly perform NAT/PAT translation between LAN and the internet  connection. I've configured DHCP pool for the local interface (GigabitEthernet0/1), which  works properly. The WAN interface (GigabitEthernet0/0) is configured to obtain its own IP by  DHCP from the ISP. I can work on the LAN computers and I can access the  internet directly from the router (using, for example, telnet and  router's ping commands). The problem is, NAT does not work properly and connection from the LAN  interface does not reach the WAN interface.

Cisco VPN :: 2901 Router - DMVPN Is Not Working

Apr 15, 2013

Trying to setup a DMVPN on out existing equipment that is currently running all point to point vpn connections. basicly its not working. my best guess is something with the config is interfering but i'm not sure the remote router (881) is always comming back with MM_NO_STATE and the main router(2901) is either MM_NO_STATE or MM_SETUP. 

I added the config for the 881, 2901 and a debug crypto isakmp and debug crypto ipsec from both routers. I have verified the Keys are correct and it is not blocking port 500. if i issue a sh crypto isakmp policy they are the same on both routers.  if you need me to post anything else i will, one note i removed the configs that were part of the point to point tunnls on the 2901 router.
