Cisco VPN ::1841 To Route From Internet Router To Internal LAN Through ASA
Jan 16, 2012
I used the GRE tunnel site to site VPN with 2 cisco 1841 routers. Behind one of the router R1, I used cisco ASA 5510, now my vpn is connect between two routers, but from R2 other site cannot access to LAN behind the firewall. From R1, also cannot route to local network, from local network can access to R1, I think cause of NAT . So how to configure to route internal network from R1 & R2 with VPN.
I am in trouble with my cisco 1841 configuration.The "what I want to" schema: very external IP ( AAA.AAA.AAA.AAA ) in the internet cloud => | cisco 1841 external IP BBB.BBB.BBB.BBB | => internal computer IP CCC.CCC.CCC.CCC
I am in trouble with my cisco 1841 configuration. The "what I want to schema":very external IP ( AAA.AAA.AAA.AAA ) in the internet cloud => | cisco 1841 external IP BBB.BBB.BBB.BBB | => internal computer IP CCC.CCC.CCC.CCC
Steps (this what I think should be done):
1. Find all packets from A by acl
2. Route finded packets throught cisco1841 directly to internal ip address
I purchased a WAP4410n for our small office to provide wireless access to our internal network to laptop users. I have configured the device as simplistically as is possible, but although I can get my laptop to connect to the AP (verified by managing the device wirelessly as well as by pinging the IP address) I can not get to any other IP address on my internal network nor the internet.I gave the device a static IP address - 192.168.1.50 subnet 255.255.255.0 with a default gateway of 192.168.1.254 which is my 2811 router. I set up a WPA-secured SSID.
A second problem I have is that if I set up my laptop wireless card to get its' IP settings form a DHCP server, it picks up a 169.xx.xx.xx ip address - it is as if the AP is not passing my DHCP broadcast / response through.
There are no commands like route-map & ip sla monitor on my cisco 1841 router, its ios version is 12.4(T1). I have to configure load balancing and failover on this router but without these commands i cant do that.
Currently i am having a scenario where i have setup RV042 and which is connected to Microsoft Forefront 2010. PPTP works fine only on rv042 subnet but i am not able to access the "internal" network of TMG.RV042 (172.16.1.1) ---> TMG [external] (172.16.1.2) ---> TMG [internal] (192.168.1.1) Is there any way through static route to access the TMG internal network through RV042 pptp server?
I have configured a L2L VPN on a Cisco 1841 ISR. I am statically NATing some of my internal hosts to IP addresses that are included in the encrypted traffic. Please note that not all of the internal hosts are being NATed. I am doing this to hid some of the real IP addresses on the inside network. I have confirmed that the VPN works, as well as the NATing of the VPN traffic. I have traditionally configured L2L VPNs on Cisco ASA 5500 series appliances, and this is my first attempt with the 1841 ISR. I just want other to take a look a see if I missed anything, or, could I have done some of the configuration more efficiently. All comments are welcome.
We have a Cisco 1841 router and checked something an unnusual (never seen before) routing table having L - local routes. if this an IOS bug or same as C - connected local routes.

VPN 1841, and static nat. I have to create VPN to connect to remote network, but problem is that they already use same subnet as mine. How to configure static nat on cisco 1841 so static nat will work and address will be translated in different IP when connection trough VPN.I have address 192.168.235.1 and I want to translate to 192.168.100.1,This 1841 is border router, and all VLNAs and VLANs routing is on 3650.
I have a Cisco 1841 with a DSL and 3G HWIC interface. I would like to setup the DSL as the primary link and then use the 3G as a backup interface. I am trying to accomplish this using the Floating Static routes with SLA object tracking.
I have tried various options, like having two tracked routes, one tracked route, changing administrative distances, multiple SLA's, etc etc.
My problem basically is that when the DSL (Dialer0) goes down and the 3G (Cellular0/1/0) takes over, that the SLA never changes back when the DSL is available again, so that the DSL can take over as the primary link again. [code]
I have an internal DVR system that I am trying to share to the outside world. We recently put in an ASA5505 and I am having trouble getting the settings correct.I want to use an external IP to access the DVR system from anywhere and have my ASA5505 redirect the traffic to the internal IP address. I assume I need to use a NAT and a route policy however can not figure out how it would be.
How can i route internal VLANs on a 3750X , my current network its small ( about 8 -10 subnets) so i dont wnat to add overhead using maybe dynamic protocol , My scenario is my stack of 3750X ( 2 switches) will be my CORE SW, i will have 2 stack more (2960S - 4 switches ) and it will connect to the 3750X with a trunk port etherchannel each link connected to a different switch, ( i was planning to use a L3 routing in the 3750X but not sure how it will works )
My core SW 3750X it will be connect with a firewall for aVPN , by a Layer 3 interface (using a static or dynamic protocol)
I've got an existing Cisco 1841 connecting to a 10Mbps Internet Leased line. With my current setup I've configured PAT for internet access for my users, and we also have some servers on site which are assigned public ip addresses, these can be accessed from the internet. Now we have procured a Cisco 1921 ISR to replace the old 1841, when I connect the 1921 with an identical configuration in place of the old router, 2 things happen.
1) The users accessing the net via the nat are able to work without any inconvenience (good)
2) My servers which have public IP addresses are unable to reach the internet and subsequently I am unable to reach them via the internet (very bad)
This two interfaces are in the global route table because there is no vrf indication. These are for internet access (a simple adsl connection) Then, I have this interface in VRF named "lan123"
interface FastEthernet0/1.23 encapsulation dot1Q 123 ip vrf forwarding lan123 ip address 192.168.143.254 255.255.255.0 ip nat enable
Now the issue.If I write:
ip route vrf lan123 0.0.0.0 0.0.0.0 Dialer0
this works and, with nat, internet works. The question is why this works without the "global" keyword? I'm going from the vrf named "lan123" routing table to global table without the using of "global" keyword.
If I try to use:
ip route vrf lan123 0.0.0.0 0.0.0.0 Dialer0 global
Basically I have an internet router (1841ISR) with 1 internal (LAN) connection and 2 internet connections. What I want to do is route specific traffic for 3 of my internally hosted services (smtp, https, etc) through one internet connection (fa0/0) and then route all other traffic through the unmanaged/dynamic IP ADSL connection (Dialer 0).
I have an issue with NAT on a Cisco 1841. See following configuration,
interface FastEthernet0/0 description Connection to LAN bandwidth 100000 ip address 10.90.0.100 255.255.0.0 ip helper-address 10.100.2.2 ip helper-address 10.100.2.3 ip load-sharing per-packet ip nbar protocol-discovery ip nat inside ip virtual-reassembly duplex auto speed auto
interface Dialer1 description ADSL connection bandwidth 448 ip address X.X.X.X 255.255.255.248 ip access-group 150 in ip nat outside ip inspect firewall out ip virtual-reassembly encapsulation ppp dialer pool 1 dialer-group 1 no cdp enable ppp authentication chap pap callin ppp chap hostname hostname ppp chap password password ppp pap sent-username hostname password password crypto map vpn ip nat inside source list 102 interface Dialer1 overload(code )
I've tried this with both a source list NAT statement, and a route-map. The router can contact hosts on the Internet:
Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 128.31.0.51, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 144/147/148 ms
Currently I have an ASA setup as a Firewall with 1 outside interface and 2 inside interfaces. Initially, the Guest interface was setup to receive DHCP from the ASA and everything was working. I'm adding router and a server for the guest interface and what I'm trying to accomplish now is the following: ASA 5505 > Airport Extreme with a public static IP (69.xx.xx.6), handling DHCP and NAT > Mac Server as DNS Server.Right now, when I connect to my Airport Extreme with any computer, I don't have internet. I don't understand what's wrong. My DNS Server has a reserved IP address: 192.168.226.2 and it's pointing to itself and forwarding the ISP DNS servers, the Airport Extreme is handling the DNS Server IP and the ISP DNS Server IP but I can't connect to the internet from the server.

What is the best way to monitor an Internet Edge router from the Internal network behind the Firewall?We want to pull more information from the edge router like netflow. We can use SNMPv3 and ACLs to keep the router secure.
But I am looking for the best config to keep both the router and firewall as secure as possible while still allowing us to monitor performance and faults.I am running an ASA and a 2821.
I want to know is it possible to check Internet speed directly in the cisco router thru any command or activating any service in the cisco router?.As it is seen most of the times internet speed offer by ISP is different as compared to clients.and Clients most oftenly not satisfied with internet speed The problem is that our ISP has given us 100MB leaased line.But when we deployed in production network the speed is same as DSL.We have reported this issue to ISP they then carried out Iperf test by connecting laptop directly with the ISP router.They have tested the speed and it shows about 94-96 Mbps and argu that it is up to the mark and there is problem at your side(i.e our internal network).Now our internal network has cisco 1841 router connected directly to ISP 3825 cisco router.Our router has minimum configuration as required to pass traffic out and in.Our internal 1841 router is connected to switch to which different clients are connected.We have performed some online tests using different speed checking websites and also perform real time tests by uploading and downloading files.The speed is much low as compared to 100Mbps and it is nearly or slightly higher then as DSL connection. how can we check internet speed in the specified scenario?Is there any command or service available in cisco router to check internet speed as we want to check ISP connection speed directly thru 1841 router?what about authenticity of online speed checking websites?Any specialize software/tool you recommend to check Internet speed in specified scenario?
I know that WRTP54G is a voip device, but it is router as well and my problem is related to routing part.I cannot access public internet servers with IP in subnet 2.0.0.0 / 8 and 1.0.0.0 / 8. In the 2.0.0.0 / 8 subnet are some akamai cdn servers (yes, the fbcdn .After some time I've found, that routing table in wrtp54g contains also entries:
which cannot be deleted. It looks like someone wanted to filter dark space when the router was developed.Is there any way, to get rid of it? I've restored to factory defaults, no change. Firmware version is 3.1.27.ETSI
I've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.
My router just dropped the internet. I checked with ISP and confirmed that their modem is fine - I can connect direct into that - but the DIR-655 won't connect externally. I've tried wireless and wired and can connect fine to the router, but it is like the firewall has reset itself or something. at the moment I'm surviving because of a 30m long ethernet cable to the modem going out the window and round the house!
My office connection have low ping to a game server that i play and i'm thinking on how to route my home internet connection to it.Home ~230msOffice ~120msThe ping from my home to the office firewall and router is pretty low since it's in the same area but going out to international connection made it jump really high when i'm at home.[CODE]
My lease router 1841 is not going behind the Juniper Firewall. i am able to ping and telnet my Juniper firewall, but when i try to ping dns server 4.2.2.2 or any other website it gives me no reply.
Below is the configuration of my Router.

ok i have setup a subnet on my uncles network on which i am running a domain with server 2008. i am using a dlink di 624 router and wanted to know if i upgraded to a 300mbps router would this increase the bandwidth within my network?i know i am limited to what i am receiving from my uncle who is also limited to what he is receiving from the ISP. im not worried about internet speed. i want to increase client to server speed for both lan and wireless.
After connecting via anyconnect client 2.5, I cannot access my internal network or internet. My Host is getting ip address of 10.2.2.1/24 & gw:10.2.2.2
Following is the config
ASA Version 8.2(5) ! names name 172.16.1.200 EOCVLAN198 description EOC VLAN 198 dns-guard ! interface Ethernet0/0 description to EOCATT7200-G0/2 switchport access vlan 2
I have an ASA 5510 configured 3 interface Internet_AAPT, Internal_Network and Server_Network. The server network works fine as is able to connect to the internet and services like port 80 work from the internet in. But from the Internal_Network can only get to the server network but not internet (6May 13 201214:17:4030201310.153.111.21253663199.47.216.14880Built outbound TCP connection 42508 for Internet_AAPT:199.47.216.148/80 (199.47.216.148/80) to Server_Network:10.153.111.212/53663 (10.153.111.212/53663). The weird thing in logs i see a connection being made but for some reason its referring to the Server_Network interface? below is my current config...

Used a pair of ASA 5520s in HA to firewall the internet edge and to firewall traffic between internal security zones such as web and application layers? If so, is this best done using different security levels or contexts?
I'm thinking of using a routed context for securing the internet edge and then using seperate contexts for the web and application networks. Contexts will route via a L3 switch.
I have a branch office connected to the Head Office through a VPN Tunnel in cisco 1841 Router. If i enable Internet for any pc in Branch Office through cisco router i cannot access it remotely from Head Office. [code]
