I have created new IPSec tunnel between branch to branch (1750 to 1750 router) and tested the FTP file transfer.I am able to logon to the FTP server and able to see the files but i could not PUT or GET the the files.Encryption happening for PING and TELNET.ie encryption not working totally between 1750 routers for FTP PUT &GET.
And there is no problem with FTP server because without ipsec,FTP is working fine and also i tested with other FTP server.
both routers are running ospf.
Also we have tried the ftp between central router 3661 and remote router 1750. Routers running IPsec and routing protocol OSPF and . I was able to do ping, telnet and also able to download file from ftp server located at central location. But I am not able to upload the file from remote router 1750 to central router 3661.
