PfSense FreeBSD on OVH Public Instance - no internet connection

I have no internet connectivity in freshly installed PfSense system.
Steps:

1. I've created OVH instance with Ubuntu and I mounted mfsbsd image.
2. After booting to mfsbsd there was also internet problem. Couldn't download anything or ping at all.
3. I copied PfSense image through SSH using local network.
4. I installed PfSense with UFS BIOS option.
5. Using OVH console I can see that PfSense booted properly after restart. I configured also reverse proxy on nginx using other server in the same local network (http://192.168.10.22/ --> https://pfsense.domain.com/). After that I can reach GUI through pfsense.domain.com URL, but there's an error after logging in and I can't do anything in UI:

An HTTP_REFERER was detected other than what is defined in System > Advanced (https://pfsense.domain.com/). If not needed, this check can be disabled in System > Advanced > Admin Access.

6. After logging in to PfSense server using console I noticed that there's also network connectivity problem.

8. I checked /etc/defaults/rc.conf and options defaultrouter and gateway_enable were set to NO. I changed them to YES, but It didn't help after rebooting.
