MxOne and PIX 501 VPN

[jensjuul]

Hi

I have two 501 PIX and I have setup a static VPN connection between them. It works great on my computers - I'm able to connect through the VPN tunnel to the servers on both sides.

Now my company is trying to setup IP telephony. We have a MxOne and it's working when it is local traffic, but when we try to set it up through the VPN tunnel it does not work.

MxOne with IP phones
local IP phones Doesn't
(Works) work

Do I have to setup anything up in the PIX firewalls?

Thank you so very much!!

This is the side, where the MxOne is one, but the PIX are almost identical.

Do you see anything that shouldn't allow traffic/registration og the IP phones across the VPN tunnel?
