I work for a company spited over two sites. Both sites are connected together via a vpn connection with two cisco 850 box.
The problem we are facing frequently (often during the morning, just after a night of inactivity), is that establishing a connection is very painful because we have to retry 10 times before success.
I've put wireshark on both computer, and I've observed that:
On the client:
-> SYN -> <- SYN/ACK <- -> ACK -> <- RST <-
On the server:
<- SYN <- -> SYN/ACK -> <- ACK <- <- RST <-
Both receive a RST (I guess from the VPN) !
I wonder what can lead to this problem ?
Anyone has face with similar problem ? Any clue how to solve this ? I think the problem may be related to some timeout configuration (because it happens only the morning)
