Hello together again,
creepy. Two days ago my PFSense wasn't able anymore to connect in anyway to my CG VPN Service. Always "decompression failure" or something like that appeared.
The final solution was to change from adaptive LZO Compression to OMIT Preference. Then this connection worked again.
And what started to work as well? The VOIP Connections. I don't know how this belongs together, but now i can register like always my softphones and make calls. I think we would have searched years to find this out...But well, fortunately finally now it works again. That is the most important!
Thanks again anyway for the interesting information you posted here and the support you gave!
Have a nice weekend
