Your ISA has the same subnet internally as externally: ISA Ext. NIC: 199.245.180.29 Sub. Mask: 255.255.255.0 ISA Int. NIC: 199.245.180.28 Sub.Mask: 255.255.255.0 This is non-functional. Either use non-routable IPs internally or use an entirely separate subnet.

I am still having problem with my ISA Server. ie with pinging from SecureNAT clients. Here are my configurations: ISP IP Address: 202.1.59.8 mask: 255.255.255.248 Gateway: 202.1.59.10 Router Ip Add: 199.245.180.18 ISA Ext. NIC: 199.245.180.29 Sub. Mask: 255.255.255.0 DGateway: 199.245.180.18 ISA Int. NIC: 199.245.180.28 Sub.Mask: 255.255.255.0 DGateway: none SecureNAT Clients with Static IP Addresses: eg. IP Add: 199.245.180.19 Mask: 255.255.255.0 Gateway: 199.245.180.28 DNS: 199.245.180.28 The ISA Server's Ext NIC is plugged into the Router's Ethernet port. The Router is then connected to the ISA via a Leased Line. Can someone figure out where my problem is. I mean what's blocking my SNAT clients from pinging the ISP Server. I've enable IP filtering and ICMP outbound but still doesn't work. As I mentioned in my previous emails, Web browsing is fine. Please, this has taken me almost a month to get this working, I really need your help. Thanks alot.
