Cisco VPN :: 2921 - NAT Ports Filtered Over Point-To-Point VPN
Feb 22, 2011
I have a Cisco 2921 configured with both DMVPN for remote sites and point-to-point isakmp ipsec VPN for smaller residential end-points.
The issue is, any ports that are NAT'd from the external appear filtered on the point-to-point vpn endpoints, but work fine over the dmvpn. Everything else seems to work correctly over the vpn. I have the nonat acl set up and the port forwards work fine from the external, but I'm not sure what's happening.
I have the configuration on the 2921 for reference.

How would I bridge a wireless connection with a distance of 400 feet? Would twoAP1262N-A-K9 be able to make this happen? Or is there another wireless bridge that you all can think of?I would be connecting one AP1262 of off a 3750g switch and at the far end (400 ft aproximately) another AP1262N-A-K9.

I have 2 cisco 1941/K9 vpn router. I have configured both with LAN ip address given by our vpn provider which is 172.10.10.1 and the other is 172.10.20.1. Both IP addresses are configured to GigabitEthernet port 0/0 on both routers.
1. Is it possible to configure our own set of ip address like 10.71.10.1 and 10.71.50.1 on the GE 0/0 port?
2. Or can we configure our own set of ip addresses (10.71.10.1 and 10.71.50.1) to GigabitEthernet port 0/1 and maintain the other ip addresses on port 0/0?
The first purpose is to have our own set of ip addresses for LAN connection and I will be able to connect or telnet whichever ip address or port is up.

Currently in place ISP WISP Point to Point network would like some pointers to exceed in doing it right. Here are some issues.ISP Fiber 50 Megs down and 50 Megs up ( Working )What Router do I use? Looking at Cisco RVS4000 at JDT Site as main router I have routers at others towers using the 10.1.19.xxx address as wans setup.Do I pull out all routers and use only one from the JDT Site?
a. Due to Port forwarding
b. Lets say main Wan is 74.144.55.159 Lan 10.1.19.1
1. Site BTT router is assign address 10.1.19.33 Lan 192.168.6.1
a. Can I setup 74.144.55.159:85 to see 10.1.19.33?
My Point ot Point radio use different IP address to separate from lan address (10.1.19.xxx) Radios (10.1.119.xxx)1. Everything is working just want to re-design everything never thought I would grow this fast with in 2 years. Hope I explain this well enought. 90% of users are out in the country without high speed internet.

how is the 1130 point-to-point bridge work in lighteight mode ?
Is this supported on 5508 and on new 2500 series controllers?
How does the WCS manage the point-to-point link?
I am aware that there is Lightweight software for the 1300 series bridges but never used one so far

I have a point to point 100mb line connecting SG500x switches at 2 locations, with these ports in a vlan together. I use layer 3 on the SG500x's to route between the two sites. I also have RIP protocol enabled to allow for automatic failover if the point to point fails (this works well).
I upgraded the ios to 1.30.59, and the connection now runs at a fraction of the speed. I have hard-coded the ports to run at 100mb full duplex, but I still only get around 12mb of throughput between the switches. I used to get about 90mb before. The provider also hard-coded the circuit to 100mb full duplex. The provider has checked the circuit remotely, and everything looks fine. I tested with a laptop at each side, and did get almost 70mb throughput. I would think this indicates some type of setting mismatch, but i cannot find anything.
I am using a backup vpn for now as some things look flaky as well (on vpn, I can use the web interface to access the SG500x on the opposite side, but on the point to point I cannot - I can ping the device though).
I have seen some references on here to shutting off STP on these 2 ports.

I have two Cisco AP 1242G and i'm trying to configurate a Point-to-Point Bridge Configuration to connect two wired LAN. Figure 1.8 [URL] I would connect two wired networks.
I tryed two configurations: Root and Non-Root AP. This way every wired PC on the Root AP can connect to the Access points, but cannot connect to the wired PC on the Non-Root AP.AP and WGB. Even this way the wired computers on one AP cannot connect to the wired PC on the WGB. This way only the wireless client can connect to the wired network. This is my network:
Root Bridge Non Root Bridge
10.0.0.1 10.0.0.2
Wired clients on the RB Wired clients on the Non RB
10.0.0.100 10.0.0.200

We have a MWR2941 (running 12.4(20)MR) router on site A and one in site B which will be connected over a Service provider L2VPN Ethernet over MPLS (EoMPLS) Network, with 10Mb Bandwidth allocated by the ISP. I have simulated this in the lab by directly connecting the two MWR's back-to-back via the Gig0/0 interface with configurable bandwidth of 10Mb on the Trunk interface.
The E1 TDM pseudowire end to end is working fine, with PTP configured for E1 timing/clocking. In addition I have a 2960-24PC-L switch connected on G0/2 of the MWR (on each end) configured with dot1q trunking. The switch will be used to connect two user groups in two seperate vlans (VlanA and vlanb) and transported across the same 10MB wan Link. Below are the requirements
1) Classify and mark Psuedowire packets E1-DATA coming from a E1/CEM interface and give it priority treatment over the WAN Link with reserved bandwidth of at least 4MB
2) Classify and mark Signalling/Timing PTP packets coming from PTP Vlan and give it strict bandwidth reservation over the WAN Link of 1MB
3) Classify and mark vlan A traffic coming from the 2960 Switch Trunk port (Connected to G0/2 on MWR) and give it bandwidth reservation over the WAN Link of 2MB
4) Classify and mark vlan B traffic coming from the 2960 Switch Trunk port (Connected to G0/2 on MWR) and give it bandwidth reservation over the WAN Link of 2MB
It is important that the E1 Traffic and the Signalling/Timing PTP packets are given priority and strict reservation so that it is not dropped in times of congestion. At the same time Vlan A and Vlan B need bandwidth reservation to give them their guaranteed bandwidth.
Currently I have tried applying policy map to the CEM interface. However, I am having trouble matching anything on the CEM input. Also I am having trouble applying a service-policy outbound on the gig0/0 (WAN Link). Also I can’t apply a service-policy inbound on the Gig0/2 interface with match statement. I have tried configuring input policy map to classify and mark PTP traffic (Vlan 902), but the MWR does not also allow me to attach a service-policy to the vlan interface. how to configure the MWR and have a workable QOS solution.

We have two locations 10 miles apart and need connectivity between them. A local provider can run a 30MB fiber connection between the 2 sites at a very reasonable cost. We would have to provide the routers however. I have worked with Cisco routers before with T1 channelized connections but am unsure how the the fiber would connect to a Cisco router in this scenerio. I need to know how such a connection to the routers at each end would take place, specifically what WIC or whatever else would be needed. I currently have a 1760 router at each site but realize that they are old and I m,ay have to replace them with newer models.

We have a point to point connection going from a regional office to the main office this is provided by a Service Provider. In our office we have an ISP and what we need to prevent from happening is that if the internet drops from the ISP we could somehow re-direct the internet traffic through this point to point connection and make it so that our Internet connection is pulled from the main office. is it just a matter of re-configuring?

This is the first outside bridge I have ever attempted. These radios are 2000 feet apart, pointed at one another. The first radio has a cat 5 (with POE) to a Windstream 2Wire wireless router.
The other radio has 3 RadioLabs AP's (with POE) connected to it. I have followed the installation guide for the GS200 ( Here) to no avail. I must have missed something but don't know what.

Is it possible to run 802.1Q on a point to point Ethernet circuit between 2 Cisco ISR routers? I need to carry multiple VLANs across an ethernet WAN circuit but not sure if a Cisco router would let me do this. I can surely lab up but was looking for expert opinion on what's best aproach to carry multiple VLAN across the WAN ethernet. Plugging the circuit to a LAN switch is not an option since this is a managed WAN router.

I have a 2911 with a Vwic2 T1 card on the remote end going to a 7206 with a PA-MC-TE1, basically 8 T1 cards. Anyway I will be ordering two point to point T1 lines and since I want it to look like 3 Meg I was thinking of bonding them. Is that still the best way to set this up? If so any concerns about setup?

Due to bandwith requirements, we need to join a network with a RV016 to a network with an RV082 via a point to point air bridge. (VPN over adls was not cutting it) fortunatelly there is line of sight.
The info
LocationA LocationB
RV016 RV082
WAN1 ADSL modem WAN1 ADSL Modem
WAN2 DedicatedIP modem WAN2 Free
WAN3..7 free
[code]....
We need LAN-B endpoints to be able to reach servers on location A and viceversa.
We pre configured two point to point radios for the tower people to install. (we could change this configs)
Topology (crude sketch)[URL]
Our questions: best port to plug the radios into the RVs WAN ports? switch ports? What rules or static routes need to be created?

How do I connect and configure my WAP54G wireless access point to my new Cable Modem? I have it connected to the modem but I cannot access it to configure it. It appears to be working but before I got the cable modem I had it connected to a router and it was set-up with a static IP address. With my new ISP, I no longer have a static IP address so I am trying to configure the WAP54G to use DHCP. Trying to access it thru the internet at 192.168.1.245 does not work.
