anyone know of a tool or a way to test to see if a port is being blocked by the routers or switches between a vpn tunnel, we have 2 sites and there is an ipsec vpn tunnel between, a machine on a vlan at main site is trying to access a machine on a vlan at remote site but can't, it can ping it, and remote desktop into it, but it uses the following ports
162: SNP Trap
4096: N2 Tunneling
4097: N2 Tunneling
1433: SQL Database
we replaced the current network hardware at main site, but the fact that i can ping and remote into it has me scratching my head, i don't see anything in router that would be blocking ports. So i didn't know if there is a tool that i could test with?
