Currently I have multiple IPs, 4 of them on the external which is working fine. Any additional IPs will cause the ISA not work (service hang). Any idea? Or is there a limitation to the IPs I can add into the Network Adapter in W2K? I wonder as to why I can add them initially and not now. I have tried to reconstruct the LAT but still no use. Please help. Wallace
