zywall 70 vpn trouble |
|
|
Hi
We have a zywall 70 on sdsl with 11 branch offices on ipsec vpn.
These have been up for 6 month without any trouble, the link is used
to host citrix app's.
From yesterday we experiment hard troubles on it.
Every 15-20 mn, vpn are down and we must reboot the zywall because it
freeze.
The cpu indicate high % usage.
Indications for diagnostique
- These troubles has begun after a 10 mns cut on the links by our
operator "for technical intervention on dslam"
- We have change the zywall (standard exchange) yesterday so the one
in use is brand new
- The conf has not been changed, and worked fine before.
- The number of vpn and traffic is the same...
- The cut in vpn seems to be linked with citrix activities : during
night, we did test of download on the vpn, and did'nt observe any
cuts.
- We have last zywall firmware
any suggestion will be apreciate.. can it be linked to operator
technichal modification on the link (mtu change ?) ? DDOS ? is there
knows buffer problems with zywall and citrix ?
(sory for my english) |

What did you change on the DSLAM? That could be why you
are having trouble now, since the trouble seemed to happen immediately
afterwards.
What country are you in?
Zyxel has support in quite a few countries. Why don't you try
contacting them (in your native language.)
