VPN tunnel via PPPoE connection
The remote site uses a PPPoE DSL connection on a wic etihernet. We have the work of setting up PPPoE, but we are unable to establish the VPN tunnel. When the tunnel is activated, since the PIX debugging logs show the following:
PEER_REAPER_TIMERIPSEC (ipsec_prepare_encap_request): fragmentation, IP packet<>
0 > greater than the effective mtu 1444
IPSec (ipsec_prepare_encap_request): fragmentation, IP <1500>packet greater than e

I tried setting the IP MTU size to 1492 and 1500 on the interface of the router Dialer but I still get the same case. You have any ideas or places to look. We are able to establish a VPN tunnel from this location with a Linksys VPN router or router Drakor. This same router also works when you are using a DSL connection, requiring no PPPoE.
Thank you
JUan
Remove this line on the router:
IP nat inside source list Dialer1 160 interface overload
because this would cause the NAT router all encrypted packets which you don't want. On the PIX, you must change this:
NAT (inside) 0-list of access splittunnel
to reference the ACL sheep or add the 192.168.50.0 subnet in the ACL splittunnel.
On the PIX, enter in the following (I know they are there already):
Outside 1500 MTU
Within 1500 MTU
MTU 1500 dmz
then save the config and rebooting, it must get rid of the MTU messages.
1500>1500>1500>

VPN tunnel via Cisco to SBS 2008 RRAS router
I need to provide access to remote users outside of ro on the VPN connection. I have a SBS 2008 Server with 1 NIC (10.1.1.1) and active VPN via the option "set up Virtual Private Network" on the SBS console, I enabled the GRE and port 1723 on my Cisco firewall so (10.1.1.254).
I can VPN to SBS internally very well and can telnet to port 1723, but cannot spend outdoors.

I have read on several posts on the topic and still think I'm missing something, I'm looking for help.
Basically, I'm now implementing multiple VPN tunnels for external connections. We strive to keep the external "private addresses" our basic using NAT network.
I can get the Tunnel to work without problems using the ACL SHEEP; However, this technique requires that our internal network is aware of their external addresses "private." Our goal is to enter an address on the inside that is NAT to the external address 'private' and then shipped via the VPN tunnel. Basically to hide the external address 'private' of our internal systems that they would appear as thought the connection was one of our own networks.
The reverse is true coming from their external 'private' network. Any information of "their" private network external origin would result in our 'private' on arrival address space.
Is this possible? I am attaching a schema, which could help.
Hello
Yes, this should be possible. Lets say you allocate 10.112.2.250 as the address that you use to present the external server 192.168.10.10.
On your ASA device
public static 10.112.2.250 (exterior, Interior) 192.168.10.10 netmask 255.255.255.255
You will need to make sure that when the system tries to connect to 10.112.2.250 it is routed to the device of the SAA.

I was wondering if there is a way to allow only one side of a vpn tunnel to create connections?
Example I have a vpn tunnel going to a site with servers that I manage. I want to be able to get on the servers (via rdp, ssh, etc.) and allow the return of traffic but I don't want the servers to be able to reach me (via rdp, ssh, etc.).
Any ideas?
I use a cisco ASA5540
Hello
You have alteast 2 possibilities
- You can configure a filter ACL on the L2L VPN connection VPN
- Long-term a solution a little messier. Mainly due to the ACL filter of VPN L2L having a slightly different configuration than the usual ACL interface format
- You can turn off (if not already disabled) feature that allows to bypass your 'outer' interface ACL all traffic entering from a VPN connection. In this way, you can control incoming VPN L2L with ACL 'outside' interface traffic.
- connections are allowed as any other Internet connection in the "outside" interface ACL if its fairly simple to manage.
If this is something you are looking for I can tell you how to get to one of them.

Hi I have a question.
I hope one of you can help me.
My problem is that I want to the internet using VPN tunnenl.
I have a VPN connection with my ASA 5505 at home.
I am able to access the entire inside of the devices. But I'm unable to access the internet.
is it possible the internet using the internet connection I have at home.
i'f played a bit with the following commands:
same-security-traffic permits intera-interface &
same-security-traffic permit intera-interface & split-tunnel-policy tunnelall
ASA version: 9.1 2
ASDM version: 7.1 (3)
Greetings
Palermo
the client that is connected via VPN you are able to ping 4.2.2.2?
If Yes, if you issue a nslookup google.com is the resolved name?
If this isn't the case, then I think that the following command highlighted is the problem:
Group Policy home-attributes VPNSSL
WINS server no
DNS server no

To connect via PPPoE (dialer) Wireless ADSL
Hello
I have a WAG200G Annex-A Wireless G modem router ADSL residential, I used as a wireless router. Now I've changed suppliers (Auntie Indicom - in India), and they have a 'new technology '. Basically, instead of giving me a DSL line in my house, now they directly give me an Ethernet cable in my house (they have a local DSL box somewhere on the roof with various Cisco switches for each household). Then, they want to connect via PPPoE by starting a Dialer on my computer, this particular Ethernet cable is connected.
Now, that works all very well, but we have more than one computer at home, and I would like to use Wifi instead of being connected at all times via the cable on my laptop.
So now my question is:
Can I configure the Linksys router so that IT don't the PPPoE dial for me? Basically this means plug the Ethernet cable provided by my ISP in one of the ETHERNET Ports and set up allowing to switch on (since there is no cable "line" adsl connected more) with my user name and password.
Anyone know how to do this, or if this is possible?
Thank you!
P.s.: I've set up the Internet connection sharing via ad-hoc wireless, which works very well, but is only a temporary solution because I don't want to use my laptop as a router...
It is not possible to configure WAG200G without ADSL line.

VPN connected, stream out of VPN tunnel
I mean that we have in place of the VPN Sites manage to sites with 2 RV042 router but it seams not as I wanted. Are you sure that each transfer of data through Router 2 will go into the VPN tunnel or it shuts down the VPN tunnel. I checked the routing table and saw that:

2 1 or wan wan IP 255.255.255.0 ipsec0 private
By default 0.0.0.0 (ip wan 1 or 2) wan1 or wan2
.........
So what you think what sense data will pass through the line, it will go through the ipsec section or through wan1 or wan2. Ofcouse each data will pass through wan1 or wan2, but it can go inside the ipsec tunnel or ipsec outside tunnel. If she goes inside the ipsec tunnel, everything is ok, but if this isn't the case, transfer of unsecured data. I'm trying to access some website is not in private ip and it was outside ipsec tunnel go, I can capture and now that you have access.
Why with linksys have 2 work as draytek product even photos follow:
Can someone help me to answer this question, thank you for your attention
1. it depends on what the tunnels of your business allows. As I've written before, there are other protocols that allows you to route traffic through the VPN tunnel. Only IPSec cannot do this. For example, if your company uses GRE over IPSec then they can route traffic through their tunnels. Your RV does not support this.
2. If it's really plain IPSec then you cannot configure several subnets. You can try to implement the security group remote as a subnet more grand, such as 10.0.0.0/8. Of course the groups must match on both sides.
3. If you want to route all traffic through the tunnel, and then try to set the local/remote security to 0.0.0.0/0.0.0.0 group. Maybe it works.
The configuration of IPSec in the RV042 does not allow extremely complex configurations. It's mainly to connect two subnets between them.

Hi all
I have a little problem concerning ASA and syslogs. I have a tunnel from site to site between a local ASA and ASA distance. Behind the ASA local, I have a central syslog server (which has no ASA as default gateway) which collects messages from all network devices and I want to get messages from the ASA remote as well.
The tunnel protects traffic between local networks behind each ASA, which includes ASA inside remote interface as well. The problem is that if I specify on the SAA distance my syslog server it does not pass through the VPN tunnel. The ASA remote sees my server syslog as being 'outside' so he's using the external IP address as the source-interface for the syslog message. Which of course does not pass through the tunnel. As much as I know there is no way to configure the interface source for logging under the SAA, that you can do on a normal IOS router.
I've found a few documents explaining this Setup on CCO, but they all imply I have extend the list for interesting traffic to access allow remote UDP/514 of the PIX traffic outside my local syslog server interface. This isn't something I want to do what I would get in routing complication in my LAN with a public IP address of the ASA remote.
Any suggestions? I thought I could use some sort of NAT on the ASA remote so that all traffic for my local network a source the remote PIX is translated on the inside interface, which in theory should pass the package via the tunnel. I did not go so far.
Any help is appreciated.
Best regards
Stefan
You can define the interface that the ASA will use to send the newspapers "syslog_ip host record.
Make sure you also do "access management".
Then the SAA should source the syslogs from inside the interface, which is probably encrypted with the crypto ACL.
I hope it helps.

Client VPN will travel not connected via 877w
Hello
I've implemented a Cisco 877w and it works very well for web access
Client VPN on my laptop connects via the 877w and authenticates on my remote work ASA5510 firewall.
Problem is after you connect to the ASA, I can not connect anything internally work network (10.0.0.0/24), ping, etc. RDP is back with no answer.
I've attached the config, can someone tell me what I am missing, might access a list?
Thanks for your help
Chris
This router is made PAT/NAT, Ipsec blocking.
Activate Nat on the ASA course remote.

Connectivity on the VPN tunnel problem.
Hello
I have a site to tunnel between the PIX506 and Cisco VPN 3000 Concentrator. I'll be spending it again ASA5510, so the tunnel will be established between the ASA and PIX. After inistial tests, I found only one box of remote network (time clock lol) is down by connectivity while tunnel between Pix and ASA (works fine with the hub). All traffic is allowed through the VPN tunnel built on SAA is? I understand it should be as long as the tunnel is running, correct? (Note: the remote clock uses ports TCP 8888 and 8889 to communicate with the server)
Thank you
If there is no filter, again all traffic should be allowed.
You need not choose L2TP connection is pure IPsec.
If you wish, you can post your configurations to check them out (you can remove sensitive information)

SBS 2008 office1 Serv2008 Office 2 need to share assets between them via a site to site VPN tunnel
Hi all.
I really need help on this one.
The office 1 installer running SBS2008 Office 2 running Server 2008.
Each firm has its own FQDN Office 1 CompanyABC 2 A_B_C of the company office.
Each firm has its own internal IP address pool Office 1 192.168.69.xxx and office 192.168.20.xxx 2.
Site to site VPN tunnel between 2 office routers Netgear SRX5308 1 and 2 Netgear FVS318G Office established and working.
Each firm has its own DNS server and acts as a domain controller
How to configure the 2 networks to see each other and be able to use assets on every network (files, printers)?
Is it so simple that the addition of another pool internal IP for each DNS server?
Thanks in advance for your help.

Routing access to Internet through an IPSec VPN Tunnel
Hello
I installed a VPN IPSec tunnel for a friend's business. At his desk at home, I installed a Cisco SA520 and at it is remote from the site I have a Cisco RVS4000. The IPSec VPN tunnel works very well. The remote site, it can hit all of its workstations and peripheral. I configured the RVS4000 working in router mode as opposed to the bridge. In the Home Office subnet is 192.168.1.0/24 while the subnet to the remote site is 192.168.2.0/24. The SA520 is configured as Internet gateway for the headquarters to 192.168.1.1. The remote desktop has a gateway 192.168.2.1.
I need to configure the remote site so that all Internet traffic will be routed via the Home Office. I have to make sure that whatever it is plugged into the Ethernet on the RVS4000 port will have its Internet traffic routed through the Internet connection on the SA520. Currently I can ping any device on the headquarters of the remote desktop, but I can't ping anything beyond the gateway (192.168.1.1) in the Home Office.
Any help would be greatly appreciated.
Thank you.
Hi William, the rvs4000 does not support the tunnel or esp transfer wild-card.

SA520w routing through site-to-site VPN tunnels
I have several offices that are connected using site-to-site VPN tunnels and all will use the SA520W (firmware 2.1.18). I currently have 3 routers in place, router tunnels created for the router B and c of router. I need assistance with the configuration to allow the guests to router site B get to the router site C. I have attempted to add a static route, but get a destination unreachable host trying to ping. Also, if I connect to the router site has via the Cisco VPN client, I'm not able to get resources on each site, B, or C.
A - the site 10.10.0.0/24
Site B - 10.0.0.0/24
Site of the C - 10.25.0.0/24
Any help is greatly appreciated.
So, that's what you have configured correctly?
RTR_A
||
_____________ || ___________
|| ||
RTR_B RTR_C
Since there is no tunnel between B and C there is no way for us past that traffic through RTR_A for two reasons. The most important reason is that subnet 10.25.0.0/24 (rtr_c) is not allowed to pass through the IPSec tunnel (it's okay to IPSec?) of rtr_a ==> rtr_b. You can't just add a statement of road because your addresses are not routable which is the reason why it fails.
Your only option is to create another tunnel between rtr_b and rtr_c. This may not be the ONLY option, but you should get what you need.
I hope this helps.

NAT, ASA, 2 neworks and a VPN tunnel
Hello. I have a following question. I am trying to establish a VPN tunnel to a remote network used to be connected to our via a VPN tunnel. The problem is that the previous tunnel their share has been created for the x.x.x.x our coast network which will serve no more time a month, but is currently still active and used. As I'm trying to get this VPN tunnel as soon as possible without going through all the paperwork on the other side (political, don't ask) is it possible to make NAT of the new network in the network x.x.x.x for traffic through the VPN tunnel.
Something like this:
new network-> policy NAT in old x.x.x.x fork on ASA-> VPN tunnel to the remote network using x.x.x.x addresses
It is possible to add the new policy, but sometimes it can conflict with the former.

VPN Tunnel access to several subnets ASA 5505
Greetings,
We spent a little time trying to configure our ASA 5505 in order to TUNNEL into several different subnets. Subnets include 192.168.1.0 / 192.168.2.0 / 192.168.10.0
Someone is about to review this setup running and indicate where we have gone wrong. When I connect via the VPN Client, I can access the 192.168.1.0 network, no problem. But fail to reach the other two. Thank you very much.
Output from the command: 'show running-config '.
