I have a simple isp topology built in GNS3, for testing (pppoe) dialers:cisco router(R1) connected to my pc network card, doing NAT translations for all the devices in the topology.I know how to configure NAT for spesific ip range, but i can't find out how to configure NAT for networks which are learned through ospf (or any other dynamic way).
View 2 RepliesI'm trying to advertise the branch LAN subnets via OSPF back to our core.I can create the OSPF adjacency and the ASA is learning routes fine. However it does not appear to be pushing the branch LAN subnets to the connected router. show ospf database reveals they're not in the OSPF database.Here is my routing config, the branches are 10.114.0.0 /16.As an aside, why I need the statics below, they appear to be necessary to reach my LAN subnets behind the EZVPN spoke sites. I would have thought the ASA would learn it automatically as I'm running network-extension mode on the spokes. [code]

A pix 515E with software 8.0(4)28 connects the inside and outside networks. There are some servers in "outside" that have addresses overlapping with the internal subnets (192.168.10.25 and 192.168.10.26), and those servers have a reverse route only to a specific subnet (172.16.5.0/24). [code) Now to the problem. 192.168.10.26 is an HTTP server. On the pages it has hyperlinks pointing to http://192.168.10.25, the browser tries to access that server and, surely, fails, as the target server is only available by sending requests to 172.19.100.1, with the packets being DNAT'ed.Is it possible to rewrite the packet's body, replacing all occurances of url... I know it's a kludge, but other options are even worse.ASA eith 8.4 software? IOS router?

I have 2 ASBR routers, AGFR01RTR03 and AGFR02RTR03, performing OSPF to OSPF redistribution in both ways for the same ***. They also do summarization for our private addressing scheme. It is all working just fine for that part (neighbors, summarization, redistribution).

Currently the OSPF network consist of 2 segment route via static route.One is AREA 0 and another AREA 10.Both network are seperate entity, only static route to route between 2 networks.But the static route do not provide the dynamically and flexibility, I plan to run routing between 2 networks via VLAN160 and VLAN162.
I still want to manitnace it was 2 different OSPFrouting domain.Can I run OSPF with differrent OSPF porcess ID?
OK. I think Im going crazy here. Im studying OSPF and I'm working on the DR/BDR election process. I have a topology where three devices (RIDs 1.1.1.1, 2.2.2.2, and 9.9.9.9) are on the same ethernet segment so they need to elect a DR. 9.9.9.9 is a switch and Im using a SVI for the OSPF interface. Van't get the darn thing to show up in the post but here is the topology.URl After OSPF came up, I noticed that router2 was selected as the DR and that switch1 was selected as the BDR. I thought initially that it was a matter of timing and that perhaps router2 just came up first and the slower SVI interface came up second. Shutdown the interfaces, cleared the OSPF process, and set the OSPF router priority on the VLAN interface to 10.

Quagga is runnign fine and network is converged, able to see all the routes.. Quagga software is logging all the osfp information includign packets,state machines,etc.I am going to disconnect a link between node a to node b. and i want to measure the convergence time of the network.What is the network convergence time?My answer is, The time taken to reflect the topology change (link down/up, network condition change) to all the routers on the topology.Some routers(close by routers to the topology change) will get converged fast, and some routers(far away from the topology change) will have the higher convergence time. we have to take the highest convergence time of the router on the topology and we can says thats the ospf network convergence time.

We have an OSPF network with four 6500 Distribution Switches. They are fully meshed and see each other as peers and are sharing routes. Off of one pair (Border) there is a setup of 3750G siwtches that go off to another network and they do not run OSPF. Between the Border Dist and the 3750G Switches we run HSRP. The 3750G side uses HSRP GP 192 and the Dist Side uses HSRP 192.There are static routes on the 3750G pointing to the Dist HSRP address to get back to network.Pings fail from the OSPF side to the HSRP address on the 3750G side.If I do a trace from the OSPF side to the HSRP address it hits one border dist switch then the other and fails.If I have static routes on both border dist switches pointing to the HSRP on the 3750side, do we need to change the metric on one dist so that it is preferred over the other or should the router Id take care of that?

I have an internal server 172.16.1.202 that is PAT to 5.5.5.103 to allow RDP connections. - This works fine from the internet.I have now been asked to allow our guest wireless (192.168.100.0/24 - DMZ) to access this same external connection.We have 2 cisco controllers, with the guest controller "anchored" in the DMZ.I cannot get this to work.Both the DMZ and inside NAT their internet connections to 5.5.5.2.
I have a 5505 with the security plus license. I have a web server in the DMZ that needs to talk with a server on the inside network but it doesn't seem to be able to. Im guessing there is something I need to do to enable the DMZ to talk to the inside network.
Here is the config.

I am trying to configure a server(192.168.5.50) in DMZ(192.168.5.0/24) to be able to communicate with a domain controller(10.5.44.220) in the inside network(10.5.44.0/24). I made some configuration using ASDM(not familiar with the CLI) but not working and it caused existing NAT not to work, for example RDP(TCP 3389) connection to 38.96.179.220

1. two way commucation between 192.168.5.50 in DMZ and 10.5.44.220 in Inside for SecureAuthPorts and SecureAuthOutbound service groups
2. NAT for 192.168.5.50 mapping 38.96.179.50 for the service groups mentioned above
3. NAT for other hosts already existing

Got a problem accessing our webservers on the inside interface from other clients on the inside interface on our ASA 5505.As in, they type in url... in their browser, and it wont work.

I am setting up a new ASA 5510 on our inside network so that we can terminate our VPN connections on this ASA. I can get the VPN to work fine however I noticed that once I turned on my VPN profiles now when I try to access the ASDM I'm getting the VPN logon page. So I decided that in order to resolve this I need a separate interface dedicated to management of my ASA.
I'm trying to come up with the best way to do this. I've got two ports on the ASA plugged into my core switch. One is on a separate VLAN from the rest of my network traffic. This is the port I want to use for management. The second will be used to route all of my VPN traffic.
So far I haven't been able to get this to work at all. My thought was that it had to do with routes, NAT and ACLs. I've been playing with them but can't get any combination to work.
I have an issue accessing the inside network of my church from VPN. This only happens when I connect from my home network. I have no problem accessing inside network of my church if I'm connected from else where (my Clear Hotspot or someone else's house). Here is the hardware detail:
At the church, we are using Cisco ASA 5510 and we have so many VPN tunnels to different churches. At home, I 'm using Cisco ASA 5505. See that attached configuration for my home ASA5505.
I'm looking for a content filtering/antivirus/antispyware appliance for my company. Right now we have an ASA 5505 at the edge. We have several outside employees connecting via Cisco VPN clients to the ASA. I need an appliance that can do content filtering for my inside network, guest network, and VPN users. That's two local VLANs and a VPN pool which are all terminated at the ASA.
I've had good luck with Cymphonix in the past, but their boxes are a bit steep for the amount of throughput I need. We'll probably be moving from a 15/15 fiber connection to 80/10 cable soon since our provider can't seem to keep us online; even with an alleged "100%" SLA. They just don't have a network capable of anything close to 100% uptime, plain and simple.
I'd like to keep the ASA running as our firewall and VPN server, so the device needs to be able to do content filtering/av/as in a transparent mode.
I have been playing around with some hotspot/captive portal software on my home network. At the moment I have Grase Hotspot setup on an old computer in the garage with a Engenius outdoor wireless AP connected to it.I would like to have Grase Hotspot loaded onto my Proxmox server inside the house and only use the wireless AP located in the garage to allow connections.My network is as follows.
Internet--->PFSense Router---->Linksys SRW2024 Switch--->Proxmox-->Out to garage into another switch---> Engenius AP
I tried it on a VM, but Grase Hotspot tries to hand out IP's to the entire network, instead of just taking connections from the AP.
I'm trying to make a very plain and simple network with the ASA 5505, I've strated from scratch over a dozen times triyng to find where I'm going wrong. My main goal is to simply create an IPSec VPN connection to my ASA 5505 and simply ping and connect to devices with the "inside network", so far I can easily create and establish a IPSec VPN Connection, but up to this point, I cannot successfully ping or access a single device on the ASA 5505 inside network.I've taken, create the IPSec profile with the ASDM wizard, add exemption for the VPN IP Pool, add access-list from this Cisco link, url...All this and I can't make a single connection to the inside network.
