SIP Only one-Way in z3 Site2Site VPN after MX Upgrade from 84 to 95

Hi,

 

we have replaced our MX-84 HA Pair with two MX-95. everything works fine except the SIP Communictaion from the Cisco phones behind the Z3 Teleworker Site2Site VPNs that worked before. 

The SIP Audio  is only One-Way (outgoging from Z3 Phone to Internal).  We havent done any other changes. 

 

It is an IPv4 enviroment 

The NAT Setting for Site-2-Site VPN was Always Set to automatic  via Meraki Cloud.


Does someone have expirienced this or a similar Problem ?

 

with regards


Robert

What version are you running?

Please, if this post was useful, leave your kudos and mark it as solved.

All on 17.10 (MX84's and MX95's)

 

We switched back to the MX-84 Pair. 

Z3 VPN Auto-Nat seems to work  fine as Before. SIP Audio now two way. Again

@KSVSachsen,

 

I suggest you downgrade to version 16.16.6, version 17.10.1 has been removed from the list of stable versions. This version was showing several bugs, mainly in performance.
