Concentrator version 3.6.7F DEFECT !

Dear All,

Until now I didn`t find any update for version 3.6.7F bug fixes on the CCO.

So far Cisco had announced that recent vulnerabilities are fixed only on "version 3.6.7F".

As my testing result here, VRRP+IPSec over TCP doesn`t work . From other posts, Load-balancing+IPSec over TCP or UDP has some issues also.

Why Cisco doesn`t response to these issues ?

Anyone tried to upgrade to version 3.6.7F without any issues ? How do you encounter the vulnerabilities announced recently if you don`t upgrade to version 3.6.7F ?

Would be appreciate for any comment .

Best Regards,

There is no official release with fix for these bugs. I tried upgrading to 4.0.1 and VRRP is working for me, may be you can try this.

Re: Concentrator version 3.6.7F DEFECT !

I would like to upgrade all of our end-customers` VPN3000s to version 4.0.1 if the quality of the code is good/stable. The Japanese are very picky about quality of the services. How do we get trust from the customers, if we already announced that upgrade to version 3.6.7F is safe, but in fact there are issues with the IPSec over TCP and probably IPSec over UDP combined with VRRP and/or Load-balanced ?

Re: Concentrator version 3.6.7F DEFECT !

Just found the following bug ID today.

CSCeb22460 Bug Details


VRRP and IPSec over TCP may not work in 3.6.7F and 4.0.1.

They work in 3.6.3.

Workaround: Use IPSec over UDP.
