如果业务软件不支持ipv6，可以使用系统本身自带的功能实现ipv6转换到ipv4，可以实现ipv6和ipv4同时使用
以下部分为chatgpt提供: )
一、linux下使用iptables实现
To use iptables to implement IPv6 to IPv4 address translation, you can use the nat table's PREROUTING chain to translate incoming IPv6 packets to their corresponding IPv4 addresses.
Assuming that you have a server with both IPv6 and IPv4 addresses, and that you want to translate incoming IPv6 traffic to the IPv4 address, you can use the following iptables commands:
# Enable IPv6 forwardingsysctl -w net.ipv6.conf.all.forwarding=1# Add a new rule to the PREROUTING chainiptables -t nat -A PREROUTING -p tcp -d [IPv6 address] --dport [port] -j DNAT --to-destination [IPv4 address]:[port]复制
Here, [IPv6 address] is the server's IPv6 address, [IPv4 address] is the corresponding IPv4 address, and [port] is the port number. This rule translates incoming TCP traffic to the specified IPv4 address and port.
To remove the rule, you can use the following command:
iptables -t nat -D PREROUTING -p tcp -d [IPv6 address] --dport [port] -j DNAT --to-destination [IPv4 address]:[port]复制
This will delete the rule from the PREROUTING chain.
二、windows下使用netsh实现：
To implement IPv6 to IPv4 address translation using netsh on Windows, you can use the following commands:
#Enable IPv6 forwarding:netsh interface ipv6 set global forwarding=enabled#Add an IPv6 to IPv4 address mapping:netsh interface ipv6 add v4tov6tunnel [interface name] [IPv6 address] [IPv4 address]#Here, [interface name] is the name of the interface that will handle the translation, [IPv6 address] is the IPv6 address that will be translated, and [IPv4 address] is the corresponding IPv4 address.#Add a routing rule to direct traffic to the mapped address:netsh interface ipv6 add route [IPv6 prefix] [interface name] [IPv6 address] metric=1#Here, [IPv6 prefix] is the IPv6 address prefix that the traffic is coming from, and [interface name] and [IPv6 address] are the same values used in step 2.#Enable IPv4 packet forwarding on the interface:netsh interface ipv4 set interface [interface name] forwarding=enabled复制
This allows the interface to forward incoming IPv4 packets to the mapped IPv6 address.
