From a server (A) in my LAN, I want to access a remote host (B) with rsh and rcp. It seems to use ports 1023 and 1022.
On the border router I tried the following ACL which works :
access-list 120 permit tcp host B host A established log
access-list 120 permit tcp host B host A eq 1022 log
But it seems to me that a spoofing B could gain access on my server (A).
Can the ACL be better ? Other possibilities ?
Thanks .
