I have a nokia ip 330 clust with NG AI. My clients are connecting via secureclient to 
create the vpn yo connect to the network.

I have two rules which concern me

1 . any >fwcluster>echorequest>accept>log   This is to allow secureclient keepalives 
---- Since I don't know there ip's ( dialup or leased) -- Is this
                            echoreply
a security risk ?. 

2. 
any>fwcluster>fw1_topo,fw1_key,ike<ike_tcp_fw1_pslogon_ng,tunneltest,fw1_scvkeepalive>accept>log.


The clients either dial via isp or connect through there leased lines. My problem is 
with the " any " as the source. Are there any security risks
and how to I overcome Secureclient problem of needing keepalive to allow the firewall 
to know the connection is still open !
Has anybody got a working example of there rules ?
tks
