之前總部和分公司之間 是用buffalo 的小AP 灌 openwrt
|
||||
|
||||
然後用strongswan 來打 IPSEC site to site VPN
|
||||
|
||||
config 看起來不是很難 (只是看起來)
|
||||
|
||||
但是實際上已經找不到當初的文件
|
||||
|
||||
所以要維護很困難(光那些RSA KEY 就不知道為何、如何產生)
|
||||
|
||||
後來採購了兩台edgerouter X 做測試
|
||||
|
||||
也用openvpn 成功的建立了 site to site VPN
|
||||
|
||||
本來想說 openvpn 已經夠簡單了
|
||||
|
||||
今天看到文章說用wireguard 可以更簡單
|
||||
|
||||
於是研究了一下，發現還真的很簡單！

||||
