I have an ASA 5510 configured with two L2L VPNs from the headquarter to two different branches.I m using the ASA “outside” interface which is connected to the internet in order to establish and configure the 2 VPN connections. Branch 1 could communicate with branch 2 through the ASA?
View 1 RepliesWe have had a successful site to site vpn working for several months now. It is an ASA 5510 at HQ to a ASA 5505 at a branch office in another state. We just added a second site to site vpn in another state this time from HQ to a Sonicwall TZ100. After plugging in the Sonicwall to the Qwest modem in bridge mode the tunnel came right up. I was unable to to ping any off the private IPs at HQ from the new branch, but was able to use remote desktop into the servers and workstations at HQ. Also all the computers show up when browsing the network from the new branch.
At the first branch we are able to ping both ways and use remote desktop both ways.When using packet tracer in ASDM on the HQ ASA and pinging from one of the IPs in the HQ protected network to an IP in the new branch network NAT-EXEMPT looks good, but when it hits the first NAT it matches on the "dynamic translation to pool 10 (10.1.255.254) [Interface PAT]" (which is the default route for all the vlans to get to the Internet.)The next NAT (subtype - host-limits) looks better and this one going to the IP address of the outside interface of the HQ ASA 5510, but then the third NAT (Subtype - rpf-check) reverts back to the "10 (10.1.255.254) Interface PAT]" and the packet is DROPPED. Also there is no VPN step in Packet Tracer after NAT.[code]
Is the problem possibly due to the fact that my 2 new ACLs for "encrypt_acl-30" fall after "access-list global_mpc extended permit tcp any any" in the config and it is running into the implicit deny all?
I'm looking for Routing Design scenarios to complete our configuration needs for remote branches. We will have two 1921 routers in each location, one with a T1 from our MPLS carrier, the other with a DSL connection from an ISP. The T1 router will have an assigned AS and use BGP to router back to head quarters. The DSL router will have an IPSec tunnel back to an ASA 5510 at head quarters. I envisions a GRE tunnel from the DSL router back to head end routers connecting to MPLS at head quarters. Not sure yet how to manipuate the routing between head quarters and the branches such that the T1 router is the primary route to and from the branches and the DSL router is for failover/backup.

The datacenter has a 5520, and the branches are connected through IPSec L2L VPNs. Branches all have 5505 or 5510's. Remote users use IPSec via the Cisco remote Client. Remote access into our data center works, and the L2L VPNs are perfect...just now that i need remote users to access the branches after Remote access VPNing (for support) i cant get that part to work.
View 2 Replies View RelatedI am working on a Cisco 5510 with multiple interfaces and requirements. I have experience with Cisco IOS, but not too much with the ASAs. I seem to be getting a bit confused on the NATing and ACLs on a firewall that was started by another employee, who is no longer here. With my current config I can get the firewall in place (we are currently using an older PIX) and most basic functions work except for two key things: 1) communication from the finance interface to the inside interface. The finance subnet has some restrictions that you will see in the ACL- we are trying to limit connections to the those systems, but they need to be able access an e-mail server on the inside. 2) communication from the DMZ interface to the inside interface. Maybe related to the first problem?

inside interface (ethernet 0/1) 130.130.0.254 and outside interface (ethernet 0/0) x.x.x.x
I have now configured another inside interface (ethernet0/2) on ASA with the IP 172.16.0.254 and I have connected it directly to another switch with a management IP 172.16.0.5.
The problem is that the two inside interfaces (130.130.0.254 &172.16.0.254) cannot communicate with each other thus the e0/2 172.16.0.254 interface cannot access the internet.
I am setting up a network that will use the 1941 router with a cellular card (HWIC) to connect to the Internet for communication with remote stations in the field. The 1941 has a static IP address (166.142.xxx.yyy) on the Internet provided by the ISP (Verizon). The 1941 is connected via ethernet to the ASA5510. The end goal is to have the field cell routers (Digi Transport WR-44-R, also static IP) connect to the ASA5510 via VPN tunnels for communication back to the servers behind the firewall. I'm not sure exactly how to configure the 1941 so that the remote router can connect to the ASA using the public IP of the 1941 router. I have the 1941 working stand alone and can connect to the Internet and pass traffic, but I tried a static NAT to translate the public IP to the private IP of the ASA and cannot pass traffic. below is part of the 1941 configuration: [code]
Do I need to use VLAN bridging to accomplish the task or am I missing something with the NAT?
Our Headquarter (asa 5510) is running a site to site vpn connection with a Branch office (router 2811). All remote users are accesing the internet through the VPN and also accesing headquarter file servers.I want to know if there is a way for some remote users to be able to use the vpn for accesing the file servers but to access the internet through the branch office. The rest of the remote users will be still accessing the internet through VPN.

I have been looking all over the place for the answer of how to allow clients on an IPSEC VPN to ping from host to host.
I am trying to set our VPN connection to route to our branch office from a VPN Client. So far I did not succeed and at this point I am stuck.At our office we have a VPN Server which enables VPN Clients to connect to our main office with an IP Range of 192.168.104.0 with subnet 255.255.248.0 and a branch office with a IP Range of 192.168.25.0 and a subnet 255.255.255.0Internally on the LAN the routing is done by our firewall, which acts as DHCP and Default gateway. It connects the 2 LANs by a leased line.When I ping an IP address in our branch office from our main office I get a reply.
Now when a VPN client connects it gets a IP Address in the range of the main office from our firewall and the client can connect to all computers in the main office network. However if i try to connect to a computer in the branch office it does not work.I tried a static route in the Routing and remote access Server (which is Windows Server 2003 R2) and I tried adding a static route to the DHCP settings on the firewall. In both cases it does not connect from the VPN Client to the branch office.Searching the internet, since the examples are all based on a setup with a RAS Server on both networks. The LANs are already "integrated"/"physicly connected" trough the routing on our firewall and its leased line.
I also tried settings on the VPN Clients machine. Settings like "Use gateway in remote network" on or off and tried adding static routes. This did not work, since the Default gateway I must use is not on the same range as the home network and returned an error trying that.What I noticed is that the VPN Client gets a route which uses the VPN CLient IP as default gateway. Makign a static route like that will work (I think), but since the IP addresses for the VPN clients are obtained through DHCP and can vary each time, there is no way (i think) to automate adding a route with, for example, a batchfile that I could give to the employees connecting trough VPN because of the variable IP.

View 2 Replies View Relatedwe installed two weeks ago a 867VAE-K9 as a border router for a medical practice.It's got two vlan interfaces for inter-vlan routing, only one Gi interface up in trunk mode to the core switch and the ATM for ADSL2+ connection to the local ISP. A cisco wap is on the secon vlan for the patients. There is a voip pbx on a linux machine that registers 5 trunks to an external provider (only one trunk is used right now, and it works fine).(Almost) everything works fine :-) Sometimes (it can be hours or days) the routing to the internet stops. The meds can still use the LAN accessing everything in it with no lag, and the patients can access the isolated SSID on a Cisco wap on the second vlan. They simply cannot surf the internet.
- DNS and local routing is fine
- the router is reachable through the Gi interface
- they can send and receive traffic to and from the 867 vlans' IPs
- the ATM, dialer 0 and virtual access are up, line protocol up
- the dialer has got the IP address negotiated from the ISP
- default route is negotiated through ipcp
- the controller vdsl 0 is in showtime! state
- from the outside we can ping the PPP peer, but not the IP of dialer 0
The only thing is the queue counter of ATM which shows drops and total output drops. Attenuation is fine, noise margin not so well. The point is that outside traffic to the internet is at low levels and the routing almost always stopped when no one was using the internet (i.e. out of office hours). It already happened 7 times in 16 days. The problem obviously is that voice traffic is impaired by the stuck router, and no med there is able to ssh into the router and re-activate the atm 0 with a shut/no shut.
It is not necessary to reload. A fast shut/no shut of the atm0 (no wait between the commands) will make it running again.We're activating the smarnet for this router to update dsl fw and ios image, but I thought I could post here before that.[code] As a brutal workaround till the update/fix, I was thinking about monitoring the reachability of some external systems and use snmp from the lan to shutdown/no shutdown the atm (though I don't even know if that would be possible from snmp on this router).
I have VPN connections in between my HO and branch locations. I am using ASA in HO and 1841 branch locations.

View 2 Replies View RelatedI have a problem with a branch office setup, and I can't for the life of me think of what the problem is.I have a remote office setup, using an ASA 5505 that is set up to establish an easy vpn connection to the central network. The connection at the branch office is a 20/5 cable modem, the central network has a 25/25 fiber connection.
The issue I have is this. Wired clients work fine at this branch office, at least 95% of the time. I have a lightweight AP there that can come up and join the controllers at the central network, no problem. I haven't done anything with H-REAP because there are really no resources locally they need that would allow them to do their work, so all traffic is tunneled back to the WLC.
Wireless clients can authenticate to the AP, and I can get 15-20ms ping responses from them all day. Latency never comes close to the 600ms proposed limit with CAPWAP. Yet, for some reason the performance of the clients is problematic. Webpages will frequently not load correctly, they experience some freezing, and with one application we use - it refuses to load completely.If we bring these same computers to an AP connected to our central network, on the same SSID, they work flawlessly.
Something about this particular location is causing a lot of grief for our users.For what it's worth, we are running WCS 7.0.230.0 and the WLCs are on 7.0.116.0. The ASA is running a pretty basic configuration, pretty much out of the box with the easy vpn configuration entered.
I'd like to connect through a VPN the HQ office to a Branch using two ASAs.I have a 5520 in the HQ and 5505 in the Branch Office.My problem is in the Branch office where I have a dynamic IP (ADSL).
I couldn't find a example this kind of configuration.
I have 3 Cisco Routers as following :G.SHDSL Router : Cisco 3845 withISDN and Branch Router : Cisco 2811.How My Network works :Branch Router has two type of connection ( First one : G.SHDSL link work as Main link and the other one ISDN Link work as Backup link )when main link goes down the ISDN link goes up ...( Note : i applied IP SLA with tracking ) ...
My Problem :i want to delete default route from ( G.SHDSL Router )0.0.0.0 0.0.0.0 dialer 3..My network works properly with these configuration but when i delete the default route 0.0.0.0 0.0.0.0 dailer3 , my network goes down ( Failover technique not works)
We installed a new ASA 5515 about a month ago for the corporate office we also have 40 branch locations that feedback VOIP, camera, and Citrix to the corp location. Each of the branch locations have a separate DSL connection with a local provider and all of them are dynamic IP addresses.
The problem I have is that I cannot figure out a access rule to make the voip traffic work 100% of the time what ends up happening is five or six random locations change IP address's every day and I could not figure out how to create a access rule for that so I create a static route with that dynamic IP and then it will change a week or so later. That's a horrible security risk and a lot of manual work.
We have AT&T Managed MPLS service are our datacenter and our branch office locations. AT&T has provided the routers and simply give us an ethernet connection. We also have ethernet connectivity to the internet through our datacenter...with our network being protected by an ASA 5520.Each branch location has a 29xx series router (voice gateway) and switching gear attached to their AT&T MPLS router. Some of our branches also have 3rd party cable internet service with an ASA 5505 to protect it from the internet. What I'd like to do is better utilize this cable modem/ASA5505 setup. Right now, if there were an outage, I would be connecting manually to the remote location to change static routes to point to the cable link and to configure a VPN tunnel between the remote and our DC.

View 1 Replies View RelatedI am preparing to move two branch offices from a point to point T1 connection to Century Link Metro Ethernet.Currently my branch locations connect to my HQ 7204 router via a channelized DS3. I have a 4507R at HQ that I will connect the ME circuit to.We will also be moving our Internet connection on the ME circuit.Our service provider Clink will hand me a single Ethernet handoff for the Internet and branch office connections. For the first phase I will connect one branch office using ME. Once that is in place and tested we will move another office and so on. Then our final step is to move our web connection to the ME circuit.Each branch office has their own unique voice and data subnet. They each have a 2801 router and a 3560 switch. The routers are MGCP gateways with only one PSTN connection, a POTs 911 line on a FXO port.
So my questions are;
1 - Should I connect the ME directly in to the 3560 at the branch offices or use the Fa0/1 on the 2801? Fa0/0 is currently connected to the 3560.
2 - On my 4507R at HQ how will I configure the ME switch port? As a dot1q trunk port?
3 - Given that ME is basically a LAN connection will I have to re IP the branch office? HQ is 10.10.1.x/24. Branch is 10.10.166.x/24 (data) 192.168.166.x/24 (voice).
4 - On the 4507R will I need to configure a vlan interface for each branch subnet?
I attached two network diagrams. One represents our current topology (MEexisting) and the second represents the new ME circuit changes (MEprojected).

We have an available 3845 with a VWIC2-2MFT-T1/E1 card. We are supposed to be getting 2-T1 lines from Verizon. I have a spare 3750 L3 switch for the core and 6 access switches.
We recently switched two of our branches to point-to-point fiber connections to our corporate office. Previously they were using MPLS connections. For branch A, the ethernet handoff of the fiber is connected directly to a Catalyst 3750 gigabit port. That port has no configuration on it. The other end of that fiber is connected to a gigabit port on the 3750 switch at our corporate office. That port is configured with an IP address that is within the subnet of branch A, and is operating at layer 3 due to the no switchport command.
Branch B currently has a Cisco Express 500 ethernet port (with no configuration on it) connected to the fiber hand off there. At first we setup a port on the 3750 at our corporate office that is connected to Branch B via the fiber in the same manner. This resulted in us receiving DCHP leases at Branch B from Branch A. Obviously not desired. Now we have the port on the corporate 3750 that is connected to Branch B's fiber configured with switchport vlan 64. I also configured interface vlan 64 on that switch at corporate with an IP address from the branch B subnet. We then set that IP address as the default IP address for devices at Branch B.
We are having trouble with both an ATM and a phone system not communicating properly at Branch B. At Branch A we are experiencing the same oddity with the phone system, but the ATM is able to communicate fully. At branch B, when configuring a Windows Vista or Windows 7 laptop with a static IP address that is known to be available, you get transit failures when trying to ping. Essentially everything seems to be able to route fine, but some traffic even after a full tcp hand shake seems to not transmit properly.
When you configure a point-to-point fiber connection from a layer 2 switch at a location without a router to a location with a Cisco Catalyst 3750 switch as the endpoint, what is the best way to configure both sides?
Currently we only have vlan 64 configured on the port mentioned on our switch at corporate, and then the switch at Branch B is essentially operating as an unmanaged switch at the moment with all ports in vlan 1.
setting up MPLS on a single T3 line. A client has contacted us to set up a 2951 at a branch location. There are 5 locations connected with MPLS.They will split off 4meg of the T3 for mpls. The rest of the 45meg would go to the internet.They have two 1841's currently set up with a T1 line in each. One 1841 connects to the MPLS and the other to the internet.When the T3 is turned up by the provider, everything, internet and MPLS, will go through it. I asked for the current configurations, but I have not received them yet and this setup is due in a couple days.Given I've never configured MPLS before and I have a rudimentary understanding of how it works, any tips or configurations? I'd hate to be stuck on site and not equipped to complete the job.
