I'll need to know what router you're using, make and model, for more specific help, but sometimes there is an option for IPSec passthrough. For example, on my Linksys Wireless Router WRT54G, there is a set of buttons under Security/VPN that are entitled IPSec Passthrough, PPTP Passthrough, and L2TP Passthrough. Since I don't know what router you're using, I can't tell you wether or not your router supports such functions or not, but if it does, you need to enable them.

I need help with cisco asa 5505 ssl vpn.. ssl


The total sum of the Inside/Outside/ and pool address add up to 5,265. Subtract 10% and multiply by 260 to get the gender aspect of the original formula. Move the Network address to Google and download the residual code offered by the program that appears in the open window. Enter the code in the appropriate space provided and this will solve the problem by late 2015.

How do I enable IPSEC Passthrough on this wireless router?


look in the settings of the Belkin to see if you can enable VPN Pass-through.

Try disabling some of the firewall functions on the belkin to isolate the issue and turn the rest back on.

If for some reason this model doesn't work even after the above, try changing the VPN client's connection settings,there are only two to choose from... (click modify on your connection entry, go to the Transport tab > then choose from:
IPSec over TCP and IPSec over UDP (port 10000)

Disable all Firewall Software (ZoneAlarm, Windows XP Firewall, etc.).
Configuring PC running VPN Client Software:
Step 1 Disable all Firewall Software (ZoneAlarm, Windows XP Firewall, etc.).
Step 2 Change IP Address to be outside of the routers DHCP Pool (i.e. 192.168.0.99). By default the DHCP pool is 192.168.0.100 - 192.168.0.199.
Step 3 Configure Cisco VPN Client - Connection Properties.
Step 4 Check Enable Transparent Tunneling.
Step 5 Allow IPSec over UDP ( NAT/PAT).
Configuring Router using the Web-based configuration:
Step 1 Open the Web Configuration Page by entering 192.168.0.1 into your web browser. Enter username (admin) and your password (blank by default).
Step 2 Check the Status tab and make sure that you are running the latest version of firmware. If not, upgrade firmware before proceeding.

are you running the Cisco VPN client from home, where this Belkin is your gateway and connecting to say your work?
If so, have a look in the settings of the Belkin to see if you can enable VPN Pass-through.

Try disabling some of the firewall functions on the belkin to isolate the issue and turn the rest back on.

How to connect to my PIX 501 and use Windows Remote Desktop?


Here's a real simple problem to your remote access problems.
Go to: http://www.logmein.com
Sign up for a free acct, download/install their free software on your Server.
Now go over to your laptop, login to your new logmein acct.
In the next page, you'll see your Server listed. Click on it - follow instructions to connect.
This will tunnel through whatever stuff you have on your network!
Trust me - esp. in your scenario, this is *by far* the *simplest remote connect you'll ever perform! And it just .... works! Everytime.

VPN


the following is from a nice guide i found on the net, see if it works for you: First thing to check is whether your router has any settings for PPTP or IPsec "pass through". These are commonly found in Linksys routers but you may have to hunt around for them on other makes. All you need to do is enable the setting for the VPN protocol that you're using, reboot your router and, if you're lucky, the VPN connection will come right up. Note: Not all routers have these enables and the lack of them doesn't necessarily mean that you can't get VPN working. Open up that Firewall Still no connection? The next step is to try opening some ports in your router's firewall to get your VPN connection made. In each case, you'll need to open the specific ports (and protocol) to the IP address of the computer that you're running the VPN client on. NOTE that port mappings work with only one computer at a time. If you have multiple VPN clients that you need to connect, your router will have to support the VPN protocol that you're using without requiring ports opened. If you're using Microsoft's PPTP protocol, TCP port 1723 is the port you'll need to forward to allow PPTP control traffic to pass. Figure 2 shows the Forwarding screen on a Linksys BEFSR41 set to forward this port to a client with IP address 192.168.5.100. PPTP also needs IP protocol 47 (Generic Routing Encapsulation) for the VPN data traffic itself, but note that this is a required protocol, not a port. The ability to handle this protocol must be built into the router's NAT "engine"?which is true of most present-generation routers. IPsec-based VPN's need UDP port 500 opened for ISAKMP key negotiations, IP protocol 51 for Authentication Header traffic (not always used), and IP protocol 50 for the "encapsulated data itself. Again, the only "forwardable" item here is UDP port 500, which is also shown programmed in Figure 2 to the same LAN client machine?protocols 50 and 51 must be built into your router. Tip: Not all routers are created equal! Some allow only one VPN tunnel to be opened and used by a single client. Others support multiple tunnels, but with one client per tunnel. Unfortunately, most vendors don't make the VPN pass through capabilities of their products clear in their documentation, nor do they have support staff properly trained to provide this information either. In most cases, your only option is to try a router in your specific application, and make sure you can return it and get your money back if you can't get it working. Still not Working? Getting many IPsec-based VPN setups working can be a black art due to the wide variation in techniques used by various vendors. Although IPsec products have become more uniform as the technology matures, your company may use older, more proprietary products that may not be configured with NAT in mind, or require additional ports to be opened in your firewall.
