VPNC over PPPoE does not route over local network

Installing and Using OpenWrt Network and Wireless Configuration
#1

Guys: OpenWRT 19.07. When the WAN was in DHCP everything here worked right on the local network. When changing the WAN to PPPoe the VPN stopped working correctly on the local network. I can no longer fire ssh for VPN networks and some pages do not load correctly. Inside the router itself, ssh works correctly for networks inside the VPN. Can anyone give me a light?

Check if MTU is correct after switching from the typical 1500 of ethernet to 1492 in PPPoE.
