Cisco Security :: Can Configure A PIX (515) As PPTP Client To Establish A Tunnel With PPTP Server
May 15, 2006
Can I configure a PIX (515), as PPTP client to establish a tunnel with non-Cisco PPTP server ? Can my PIX initiate this type of connection ?Today, I use a PC with PPTP client to establish this and I want replace this with a PIX and I don´t want depends of a PC.
Does RV082 can establish PPTP VPN connection as CLIENT? (i'm aware it can provide function of VPN PPTP server but could not find if it can act as client).To explain further: I'm based in Europe and use US VPN to access some US services like Netflix, Pandora, etc.. (i'm paying for US VPN account as service so I have no other choice than PPTP). I would like to establish permanent PPTP VPN tunnel with remote server so all computers in the house can go through tunnel when i browse for Pandora or Netflix for example (is this router capable of routing policy too so not all the traffic would be routed through tunnel?)
I'm trying to configure 1700 K9 router to act as PPTP client and connect to Microsoft VPN server (in order to enable all clients on LAN to seamlessly access host on remote location). [URL]
I'm using GMS3 to test everything in lab environment. I managed to connect to Microsoft VPN server but the connection drops immediately. Below is debug info from router R1 (router R2 just simulates host on LAN) and configurations for both routers. The only clue I got from debug is that immediately before closing connection there's a message "CCP: Failed to negotiate with peer"...
R1#sh debug PPP: PPP detailed event debugging is on MPPE Packet Details debugging is on
I'm trying to set up a permanent VPN connection for an Expat. We've got an RV042 set up on site to act as the server, and an RVL200 as a client. This RVL200 will be behind a home router, so it needs to initiate the connection every time; the site side router won't be able to see it behind the Expat's home router.I've got a PPTP server set up on the RV042, and I'm trying to get the RVL200 to connect to it as a client. Is there any way to do so, or will we need to go with another option? Because on the RV042, I see no way to set up an SSL server of any kind; only a direct SSL Tunnel, which won't work as again, the RV042 will not be able to see the RVL200.
My ISP has just implemented a new network on the cable infrastructure which uses a PPTP authentication method. It works on my Cisco RVS4000 router as there is an option to set PPTP as the WAN type. The only trouble with the RVS4000 is that the performance is very poor, hence I am trying to get it working with a Cisco 1921. I have looked high and low and I cannot find an sample of a Cisco router functioning as PPTP client to a ISP.Enclosed is the screen shot of my Cisco RVS400 with the options etc.
I have a remote location that has a Linksys/Cisco RV042 router [URL] that allows PPTP connections based on username and password combinations. There are no intermediary routers between this device and the internet - only a DSL modem. A secondary WAN connection is not present.
I am able to dial into this VPN using the Windows XP and Windows 7 dialers from any of my local free-wifi locations(e.g. Starbucks). I WAS able to connect to this VPN connection from my house when my home router was a Buffalo brand router.
I have replaced the Buffalo router with a 2620(non-XM) that is connected in ROaS fashion to a 2950 switch. I need some guidance on what in my config is not allowing me to connect to this remote site.
Home network info: Local subnets : 192.168.x.x
Remote network info: Local subnet : 10.214.x.x
The Windows XP dialer client indicates that the username and password challenge is where the connection fails. It ultimately gives me the error code 619. I have performed a Wireshark packet capture of an attempt to connect from ip 192.168.10.11. This packet capture shows multiple "Configuration Request" packets being exchanged between the two endpoints, but does not ever show an exchange of authentication.
My nat translation table shows an entry for both a GRE tunnel as well as port 1723 between 192.168.10.11 and the WAN port of the RV042 when attempting to establish this VPN.
I have attached my 2620 configuration for your review.
I have two offices connected with an IPSEC VPN tunnel using RV220W routers. The Tunnel works fine for local users between the two sites(Site 1:10.0.0.x; site 2 is 10.0.2.x). I have also set up PPTP users for remote access. PPTP users that connect to site 1 cannot access site 2 and vice versa. The PPTP users have no trouble accessing the resources on the site that they connect to. I have tried activating RIP and adding various static routes with no success. If I PPTP connect to site 1 and I tracert to an IP address on site 2 the route goes to the site 1 router and then goes to the internet(connected to the site 1 router) where it stops.
I need to establish PPTP VPN to 877 modem/router from Internet.The VPN client is a Windows XP standard VPN client.I configured the router basing on the document: "Configuring the Cisco Router and VPN Clients Using PPTP and MPPE". url...And... It works quite nice BUT only when I use PAP protocol to authenticate the user.When I try to use 'MS-CHAP' or 'MS-CHAP v2' I get error 691 on the client side("Access was denied because the username an/or password was invalid on the doman.") [code]
I am trying to configure a Cisco 871 to act as a PPTP VPN server on my home network. I have referenced Cisco's documentation regarding this which I will include below as well as a copy of my current running configuration and terminal monitor information from when I attempt to establish a connection.
When I attempt to connect from a Windows machine I receive the following error: 'Error 807: The network connection between your computer and the VPN server was interrupted.' 'The remote device won't accept the connection.'When I attempt to connect VIA my mobile, I get 'The server has hung up'.The 871 does detect the incoming connection which can be seen from the terminal monitor output: url...
For the past week, I have tried to setup the PPTP VPN server on the RV180. The setup was straight forward, but I could not log-on no matter what I tried. I decided to call Cisco small business support, and as I was talking to the engineer, it mysteriously started to work. I was puzzled and somewhat embarrassed because I'd hate to admit it was an id10t problem on my part. As I tried a few different configurations, I began to realize there might be a limitation in the RV180 PPTP VPN server with the current firmware (220.127.116.11).
In short, the RV180 PPTP only works with 192.168.xxx.xxx/24 subnet. My setup has 3 vlans: vlan1 in 172.xxx.xxx.xxx/24 subnet, vlan2 192.168.0.xxx/24, and vlan3 10.xxx.xxx.xxx/24. My originally plan was to keep vlan3 isolated by disabling inter-vlan routing, but I needed a way to manage a couple of devices on vlan3 remotely, thus I wanted to setup a VPN in the 10.xxx.xxx.xxx/24 subnet. This turned out to be the reason why it never worked before. Today when I called Cisco support, I assigned the PPTP VPN server a 192.168.0.xxx ip range, and it worked. Later, I tried assigning 172.xxx or 10.xxx ip addresses to the PPTP VPN server, and they both failed to work. I created another test vlan4 with 192.168.2.xxx/24 subnet, and assigned the PPTP VPN server to that vlan, and it worked again.
I'd like to mention that I already configured the 10.xxx.xxx.xxx/24 subnet with a few devices before I replaced my router with RV180, and I don't want to have to change and test the setup of all the devices. Another reason I want to have my VPN server outside the 192.168.xxx.xxx range is that it's way too commonly used by wifi hotspots that it increases the chance of wifi and vpn in the same subnet.
I can test a few more configurations, but I think the results will be the same. Perhaps Cisco should test the RV180 in the lab to confirm what I found.
So if the PPTP server is enabled, and "Block MAC address not on the list" is enabled under the DHCP settings, will the PPTP client get an IP address?Similarly, if the PPTP server is enabled and the range of IP addresses configured on the PPTP server screen is outside the IP range of the router due to a subnet mask (like 255.255.225.248 for example), will the IP still be assigned to the PPTP client? If assigned, will that IP have any connectivity to the LAN?
I possess a RV220W (firmware 18.104.22.168) but I can't seem to work with the PPTP server on one VLAN only.
My default VLAN is in 192.168.1.1/24. I created a VLAN ID 10 in 192.168.50.1/24 inter-vlan routing : disabled and Device Management : disabled. (Menu Networking > LAN > VLAN Membership and Multiple VLAN Subnets).
Then I configured a PPTP server on the IP range 192.168.50.200 to 192.168.50.210.
To finish I created my user. (Menu VPN > IPSEC > VPN Users).
The PPTP tunnel is working, but on all my local network and not only the VLAN ID 10.
we are not able to connect to a outside PPTP vpn server;The scenario is this :Connections are started from inside netwok to a VPN server on the outside zone.
I have add these configs and still not working.policy-map global_policy class inspection_defaultinspect pptp ?i also have a acess-list for it.access-list inside_access_in extended permit tcp object inside-network any eq pptp access-list inside_access_in extended permit gre object inside-network any access-group inside_access_in in interface inside? I am missing something or this is all configs i have to get done ?
I setup my Windows 8 desktop for a PPTP VPN server so I can connect my iPhone 5 to it.Using the Cisco Connect Firmware, as I was having internet speed issues with the Smart Wi-Fi Firmware and I wasn't loving the interface of the Smart Wifi Firmware anyway.According to the router the firmware is up to date. All three VPN settings are enabled.PC is set to a static IP internally. 192.168.1.116 to be precise.PPTP port forwarding (1723) is set to the PC's static IP, though I have tried without port forwarding and it didn't work either.If I have my iPhone connected to the wireless network and point it to the internal IP address of the PC, I can connect to the VPN.If I bypass my router and hook my desktop directly to the modem (and point my iPhone to the IP that gets assigned to my desktop from my ISP) I can connect to the VPN.But if I have everything hooked up normally and try to connect to the VPN from my iPhone (using the IP address my ISP assigned to the router), I get a PPTP server not responding error.
We have just acquired a Cisco RV120W Firewall Router and we are experiencing issues with this router. I've read some threads related to port forward issue with RV120W before writing this new topic.
We have 2 locations (site A and site B) connected with a Site to Site VPN (PPTP) running under Windows Server 2008 R2 with TMG 2010. This Site to Site VPN worked very well until we replaced our old router with the RV120W at site B. Since this moment, our engineers are not able to make the site to site VPN work again. The TMG box are located just behind the router.
We have followed some threads about Port Forwarding but it did not solve our issue (others port forwarding rules for RDP for example work). Our RV120W is running the last stable firmware (22.214.171.124) provided by Cisco.
I have configured PPTP Server on RV042, and created 3 accounts. I am able to connect from Windows PC without any problems.
In the router's logging utility, there doesn't appear to be any log entries indicating either successful or failed attempts to connect to PPTP server. The only access logs I see are for access to the router's configuration utility. Is there a way to view PPTP access in the router system log?
I am trying to allow PPTP traffic through my Linksys WRT320n to a PPTP VPN server on my home network.The Linksys WRT320n is running firmware 1.0.05 build 002Mar 31, 2011.I have created a Port Forwarding rule on the Linksys to allow TCP & UDP port 1723 through to my internal IP of the PPTP VPN server,but everytime I try to connect with a PPTP client from outside of my network I get a connection error on the client.Checking the PPTP VPN servers logs I see the following errors (Please note all IP's have been masked) Mar 2 11:15:07 ap-01 pptpd: CTRL: Client x.x.x.x control connection startedMar 2 11:15:07 ap-01 pptpd: CTRL: Starting call (launching pppd, opening GRE)Mar 2 11:15:07 ap-01 pppd: pppd 2.4.4 started by root, uid 0Mar 2 11:15:37 ap-01 pppd: Exit.Mar 2 11:15:37 ap-01 pptpd: GRE: read(fd=8,buffer=41fe30,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logsMar 2 11:15:37 ap-01 pptpd: CTRL: PTY read or GRE write failed (pty,gre)=(8,9)Mar 2 11:15:37 ap-01 pptpd: CTRL: Reaping child PPPMar 2 11:15:37 ap-01 pptpd: CTRL: Client x.x.x.x control connection finished
From looking at the above errors, it seems as if the Linksys isn't forwarding GRE through to my PPTP server.I have tried various settings, including enabling and disabling the PPTP Passthrough option on the Linksysbut still can't get PPTP to work.What is the correct way to get GRE traffic forwarded through the Linksys?
I have a situation where the site-to-site tunnel is already established using PPTP IPSec VPN with non Cisco Gateways terminating the link on each end. These non Cisco Gateways do not support L2TP tunneling, and there is no plan to change them.Beyond the Gateways on both ends, we have a Cisco 4500 series switch. We need to forward the 802.1q tagged VLANs between the two sites. Is it possible to use 802.1Q tunneling in this case, going via a PPTP tunnel ?
Cisco's setup uses dot1q-tunnel over a L2protocol-tunnel to preserve the original client VLAN tagging, so does this mean that the only option we have is to setup a L2TP tunnel at the Cisco device endpoints, and have that tunnel go through the existing PPTP tunnel (established between the 2 non Cisco VPN Gateways) ?
I have a 2821 ciso router and i want to setup a vpn for my windows domain users , they must to reach the domain from outside. There is posibile to intregrate Active directory auth with pptp running on 2821 router? kind of dialin via radius server(IAS running on windows server 2003).
I have remote branches that connect to the corporate office as a site-to-site VPN. Now the clients at the branch are getting an application that is using an unsecured port (tcp/23). I would like to use a set of ASA 5520's that I have at the corporate office, with the AnyConnect license on them. I want the client machines to establish a tunnel from the client to one of these ASA's. The ASA' then would have a connection to the VLAN that the receiving server is housed on. The trick is to just establish the tunnel from the client to the ASA that will allow the IP of the client to not be translated. So I would use the ASA as a security 'pass-through' for the clients that use this new application.
I've been labbing on my asa5505 at home, setting up different VPN solutions for testing purposes. However, I can't get my anyconnect client to establish a DTLS tunnel when connecting (anyconnect only shows tls, and does not display any errors about not connecting with dtls)I have set dtls port to 444 and this port is open on the other side.
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 a user in LAN which needs access to remote PPTP server. My router uses NAT NVI for some reasons to provide internet access.
Problem is what tcp/1723 is NATed successfully and it appears what GRE traffic is NATed as well, but GRE packets are NOT passed back to user on LAN. Config is that simple:
interface Fas4 ip address x.x.x.x x.x.x.x ip nat enable interface Vlan1 ip address 10.0.0.1 255.255.255.0 ip nat enable ip access-list extended nat_clients permit ip 10.0.0.0 0.0.0.255 any ip nat source list nat_clients interface Fas4(code)
don't steer the topic from PPTP to IPsec and other types of VPN which is more secure than PPTP,,,,etc have got this scenario windows 7 is acting as vpn client at home and windows XP is acting as vpn server at workAt home (LAN address is 192.168.10.x/24)And I configured windows 7 as VPN client same as here [CODE]
