The connection tracking timeout is 500 s afaik, maybe GRE is NATed on one of your gateways? A possible explanation would be that east does SNAT on GRE packets or west does DNAT on GRE ... so when east tries to reach west, the packet is SNAT'ed or DNAT'ed and therefore doesn't reach west, but when west tries to reach east, connection tracking information is set up on both routers so it works ... until the timeout expires.
