Hi list, we have two SuSE 8.0 (kernel 2.4.18 and all the latest patches) running on two sites, connected via internet. Server A has public ip address and server B is host on private LAN behind NATed gateway. Now we exported a directory on server A via nfs. At server B we mount this directory. For our firewall (iptables) we opened upd ports for rpc (111) and nfs(2049). And after each reboot we have to add/modify the mountd port (got with rpcinfo -p localhost). But I think there must be an exact definition of what to allow for nfs on client and server side. But what? And we have a very poor nfs performance. Doing an "ls" on one of subdirs with few files is ok, but with another subdir which contains 100+ files this proccess doesn't return in proper time (it takes minutes!!!). Any idea? Thx, Oliver
