wireguard配置问题求助

qxwo

[Interface]
Address = 10.0.8.1/32
SaveConfig = true
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -A FORWARD -o wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o enp0s3 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -D FORWARD -o wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o enp0s3 -j MASQUERADE
ListenPort = 51820
PrivateKey = xxx

[Peer]
PublicKey = xxx
AllowedIPs = 10.0.8.0/24, 10.42.0.0/32
Endpoint = x:51820
服务端上述配置，客户端没设置PostUp ，PostDown
双方能ping同10.0.8.x，无法ping通10.42.x.x
这种情况需要如何配置呢，要单独配置iptables 转发吗
