Side2Side 問題
Hi小弟最近遇到了個問題
我目前三個點互作side2side VPN
ASA-3後段是一段Server用網段10.222.0.0/16
一段是SSLVPN用的192.168.78.0/24
分別與ASA-1和ASA-2做side2side
正常設定都沒問題
但ASA-3與ASA-1建立的部份在過一段時間後
ASA-3後SSLVPN用的網段192.168.78.0/24會突然的不通連不到
但ASA-3與ASA-1的都沒問題，設定值是一樣的
需在其中一邊的設備上下clear ipsec sa peer x.x.x.x
讓ASA-3與ASA-1重建才會正常
但一段時間後就又不能了
指令檢查是正常的
ASA-3# sho crypto isakmp sa
IKEv1 SAs:
Active SA: 3
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 3
1 IKE Peer: 6.22.15.250
Type : L2L Role : initiator
Rekey : no State : MM_ACTIVE
2 IKE Peer: 12.21.101.253
Type : L2L Role : responder
Rekey : no State : MM_ACTIVE
3 IKE Peer: 6.22.15.220
Type : L2L Role : responder
Rekey : no State : MM_ACTIVE
There are no IKEv2 SAs
show ipsec sa 時正常的狀況下是能看到192.168.78.0/24的資訊
ASA-3# show ipsec sa peer 6.22.15.220

然後有問題時會跳出以下的log

請高手求解
