we have establised site-to-site vpn & it is been working for quite a long time, now the problem is very often say 30-40 ping requests i get 4-5 request timed out, that time my ssh sessions via vpn getz disconnectz & again i need to start a separate ssh session to the vpn to my remote end. the vpn's public IP address pings perfect without any request timed out, only problem is the vpn private address where i face the problem, i doubted the ISP, but they are very clear the there is no packet drop. can you help me this regd. what went wrong & what is making my vpn sessions getting disconnecting often?
Note: there is no problem on the remote end server also, its not only with 1 ip address on the remote, itz for all the private ip address. & that it is happening only from my end & not from any of our other networks, bcoz they can ping perfect & working fine when connecting to the remote end where my vpn is also connected.
