//Given (packet source, input interface) and optional (dst, oif, tos):
//- (main) check, that source is valid i.e. not broadcast or our local address.
//- figure out what "logical" interface this packet arrived and calculate "specific destination" address.
//- check, that packet arrived from expected physical interface.
这样key协商的报文就无法通过协议栈发出,从而导致IPSEC VPN无法工作。
1.ipsec vpn 配置双地址(不可行)
2.修改fib_validate_source,如果报文from tun,passby it!(可行性不大)
3。不知道能否通过修改源路由或者其他方式能否解决这个问题?
