I am in Seoul(router B), remote office is in China.
Remote router(router A) is Cisco 2610, WIC-1T, VIC-2FXO, 128Kbps internet Leased line, Serial interface IP use unnumberd ethernet 0, ethernet 0 ip is same as following "show run ".
In the Seoul , ping to router then "time out"(also telnet) but,
ping to Server in the router A's ethernet network then icmp "OK".
So, After router A's reloading, ping to router then icmp "OK" in about 20~30 Minutes, ping is "time out".
But Server is always icmp "OK".....What happen?
I can mail to you who want it, "show tech"
"show run" & "show version" for reference,,,,,,(IP Address is false for security)

What IP are you pinging/telnet to (192.168 or 61.142)? Try and add a loopback and see if you can ping/telnet to it.

Any access-lists (on either end router)?
Any VPN acls?
Did you add loopback and ping it?
Enable debug on routers to see if ping is received and replied to (eg. 1)debug ip packet or 2)debug ip packet 101 detail or 3)debug ip nat - to eliminate nat as the cause, shouldn't be but you never know) ?
Does show log indicate anything?
