[FW-1] Secure remote Problem

[robert lewis <[EMAIL PROTECTED]>]

We have a checkpoint firewall R55 ,and have configured remote access
vpn(which was working perfect until now)we have a peculiar problem
,whenever any securemote user tried to create a site he is thrown the
authentication challenge and after IKE just hangs ending in "failed to
communciate with gateway x at site x"
When i check the firewall logs i am able to trace accept for IKE _topo
and IKE but nothing beyond that no drop /encrypt nothing

AUthentication:Hybrid firewall username/password


I have carried out following steps

1)Am able to telnet to fw ike topo port from VPN client machine
2)CLeared the Ipsec and Ike sa (to counter corrupt ike tables)
3)Have checked IKE over tcp enabled
4)The ICA certicate is valid
5)users are valid

Still no luck...the IKE just hangs after the authetication prompt and
ends in "failure to communcate with site x)

Please advise

HELP DEEPLY appreciated
