Configuring the TunnelGuard check using the SREM
Before an authenticated client is allowed into the network, the TunnelGuard
application checks client host integrity by verifying that the components required
for the client’s personal firewall (executables, DLLs, configuration files, and so
on) are installed and active on the client PC. For more information about how the
TunnelGuard check operates in the Nortel SNA solution, see “TunnelGuard host
integrity check” on page 37.
If you ran the quick setup wizard during the initial setup or to create the domain,
the TunnelGuard check has been configured with default settings and the check
result you selected (teardown or restricted). You can rerun the TunnelGuard
portion of the quick setup wizard at any time by using the steps at “Using the
TunnelGuard Quick Setup in the SREM” on page 172.
