Did you look at the CHANGES file?  There are new settings for NAT.  If you are using the same settings as in 1.8, there is a posiblity that you will have problems depending on what settings you have (which you did not include in this message).

Also, I would recommend 11.5 since there was a one-way audio issue fixed related to using the two new NAT settings.
