I've configured VPN tunnel with help of the url: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00807ea936.shtml. The tunnel comes up and from router with dynamically assigned IP I can access to other side only to Linux box. From fixed IP side (PIX) I cannot access device on other side except from Linux?? M$ and *nix boxes use the same gateway? Any idea?
