两个网络上的两个 NIC 的 IP 路由
我正在重写这个问题以增加清晰度和社区性。
我有一台服务器，上面有两个不同的网卡，一个是板载 10GB 以太网设备eno2，我已将其设置为 MGMT 网络上的 IP。第二个网卡是带有 4 个 10GB 端口的英特尔卡。我使用 802.ad 链路聚合方法将这些端口绑定和桥接，并为接口br0分配 LAB 网络上的 IP。
文件服务器和GPU服务器目前通过LAB网络进行通信，速度非常快。
所有网络配置都在 netplan 中，但我一直在手动编辑规则以ip尝试找到正确的配置。从那里我可以相应地配置 netplan。
问题
应如何配置 IP 表和规则，以便两个 NIC 都可以访问互联网，并且回复流量来自最初接收流量的接口，即保持在同一个网络上？
这个问题与我能找到的任何东西都非常接近，但我仍然无法使出站流量正常运行。
默认表中的路由
user@server1:~$ ip r s tab 254
default via 192.1.1.1 dev eno2 proto static
10.10.0.0/24 dev br0 proto kernel scope link src 10.10.0.71
192.1.1.0/24 dev eno2 proto kernel scope link src 192.1.1.105
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 linkdown
第二张表中的路线
user@server1:~$ ip r s tab 102
default via 10.10.0.1 dev br0 proto static
测试
我可以从局域网上的另一台机器（在第三个网络上）ping 服务器
❯ ping -c 1 192.1.1.105
PING 192.1.1.105 (192.1.1.105): 56 data bytes

从服务器我只能 ping 出eno2设备
user@server1:~$ ping -c 1 -I eno2 1.1.1.1
