How do you connect to VPN Concentrator behind your home router? do you use Cisco VPN software? and what is the IP address range that your concentrator give to VPN client? <br />
Make sure that range is not overlapping with your existing network and all other networks have a route for your VPN network, which should point to your concentrator inside interface.

It could definitely be lrmoore's suggestion. &nbsp;The other thing it could be is that your home router doesn't support VPN pass-through. &nbsp;I have come across routers that don't support it (check the specs) and the VPN seems to connect but you then get no connectivity (as you are experiecing).

<div class="content wysiwyg-content">
When connected at home behind my router (cable modem access), I connect into our company's vpn (Cisco VPN Concentrator 3000). &nbsp;I login fine, but when I try to access the various file server and even the mail server I don't get a connection. &nbsp;I try pinging the ip addresses of these servers and nothing.<br />
<br />
At home, if I am directly connected into the cable modem and then connect into our company's vpn, I can access the servers.<br />
<br />
Please help,<br />

VPN connection cannot access company network servers when connected at home behind router.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
