Internet through vpn working incorrectly

Hi all!

I'm trying to construct the following scheme for the users. Some of them went to the Internet directly from the device through NAT, some access to the Internet via a device located at the other end of the gre-ipsec tunnel. But here the problem occurs. Almost all sites are not opened (except Google), though I can perform ping and traceroute to them (of course, through vpn). I thought that the problem may be in cipher and I tried to delete the IPSEC, leaving only the GRE tunnel. But the problem is not solved.

What could be the problem?

Thank you!

have you tried reducing mtu size of hosts using gre tunnel? - had similar issue with a gre tunnel and hosts unable to access some websites. this document explains reasons why:
