ok i have site A and B
Created GRE Tunnel between site A and B
site A networks x.x.x.x and y.y.y.y site B networks c.c.c.c
so have routed networks via tunnel. x.x.x.x works with c.c.c.c with no problem all good
y.y.y.y doesn’t work. c.c.c.c doesn’t see y.y.y.y.y
while y.y.y.y is able to ping c.c.c.c router end but no further no devices on c.c.c.c are accessable
where could be a problem. is it NAT problem? And how to fix ? GRE meant to work with many routed networks via tunnel
this can be closed found the problem all networks works great now
