IPSec through F-Secure PSB Firewall

Got F-Secure PSB and IPSec VPN to my office and can't get those propely working together.

I am accessing Windows fileshare and webserver on remote machine but connection is still laggy and slow.

I have allowed IKE, ESP, IGMP, Windows networking, UDP and UPnP broadcast on firewall.

Missed something?

Re: IPSec through F-Secure PSB Firewall

Sorry for the confusion on my side. 

In order to investigate this you could try to do a packet logging as described here.

You could also try to temporarily create a test firewall rule to allow all the traffic between 2 test machines.

 

If this rule doesn't work them some other component could be affecting the connections.

Re: IPSec through F-Secure PSB Firewall

Hello,

 

Many IPsec-based VPN software have their own personal firewall integrated, sometimes based on the ZoneAlarm engine. FSAV PSB also has a built-in distributed firewall and the two can cause conflicts. Possibly you need to disable the VPN client's firewall driver or service to make things work smoothly?

 

Yours Sincerely: Tamas Feher, Hungary.

There is no personal firewall in any known VPN clients.

Re: IPSec through F-Secure PSB Firewall

Hello,

 

The Checkpoint VPN client software used to include a Zonealarm personal firewall engine, with the driver name "vsdatant.sys" and that one needed to be disabled before it could be used on the same computer with F-Secure Client Security.

 

(However, that was several years ago and may no longer be true. Nowadays most VPN clients are SSL-based, not the complicated IPSEC things.)

 

Best Regards: Tamas Feher, Hungary.

Re: IPSec through F-Secure PSB Firewall

Did i named any vpn software or other firewall applications than F-Secure PSB?

I am not using Zonealarm or Checkpoint VPN.

I am using Zyxel IPSec vpn client (based on Greenbow code) and that F-Secure PSB.

Re: IPSec through F-Secure PSB Firewall

Well, you do!
A bit of research revealed that the Firewall-Drivers Zyxel implemented are from ZoneLabs.

@Ben please escalate. Deutsche Telekom is using Zyxel routers in business environments during the upcomming VOIP-Transition.

A propper step-by-step advise is needed, even better fix the interoperability.

@itsupport could you open a support ticket so we can better understand and investigate the issue.

 

You can refer to this thread and provide an fsdiag of an affected machine to speed up the process.
