A user connecting from Vista 64 with the Cisco AnyConnect client was getting a “The VPN client was unable to successfully verify the IP forwarding table modifications. A VPN connection will not be established.” error when trying to connect. No changes had been made to the concentrator configuration which is an asa5520 running 8.0(3).
Via ASDM, there was a syslog notification of “SVC Message: 17/ERROR: Unable to successfully verify all routing table modifications are correct.”
- What is the correct way to enable IP-forwarding in MacOS X? More specifically, what is the MacOS X command line quivalent of the following two Linux commands: echo 1 /proc/sys/net/ipv4/ipforward iptables -A FORWARD -j ACCEPT mac-osx iptables ipfw ip-forwarding.
- Detects whether the remote device has ip forwarding or 'Internet connection sharing' enabled, by sending an ICMP echo request to a given target using the scanned host as default gateway. The given target can be a routed or a LAN host and needs to be able to respond to ICMP requests (ping) in order for the test to be successful.
Also annoyingly, the license only supports 2 clientless ssl vpn connections and the ssl vpn client appears to use a clientless connection initally which fails to shut down then the ssl client fails to connect, which prevents future logins with not error on the client side due to the licensing.
Also, capture filtering settings enable you to see the system pf configuration file for Mac as well as the AnyConnect filtering configuration files. For Linux, iptables and ip6tables outputs are visible in DART even though access to most of these configuration is restricted unless the DART tool is run via sudo.

I found this article which linked the proble to Adobe Photoshop. The user had installed the photoshop trial recently and when he disabled bonjour for windows, which was installed by photoshop, the VPN worked fine.
I installed Bonjour on XP 32bit and could not reproduce the problem. Perhaps it’s a Vista 64 issue. It’s a small enough of an edge case that I don’t think I’ll try to reproduce. Photos duplicate cleaner on mac.
