You deploy a pair of SteelHead appliances in-path. At the server-side, there is a firewall inspecting traffic between the SteelHeads. The firewall must see the original client and server IPs and is configured to drop packets where the same host pairs and port pairs are reused within 30 seconds of termination. Which addressing mode would workaround this issue?
A branch has a Virtual SteelHead VCX75-5H. Recently, staffing levels have changed and the best model for the branch is now a VCX555-L. What is required to downgrade the model?
You plan to downgrade a SteelHead from RiOS v9.0.1 (Apr 17 2015) to 8.6.3 (Aug 7 2015). The appliance was previously running v8.6.3 but was factory reset after the upgrade. Will this be successful?
Refer to the exhibit.
A connection times out when Client41 and Client42 attempt to either establish an HTTP session to Server31 or an FTP connection to Server32 after not connecting to them for some time. The very next attempt to connect to these services done immediately after the failure seems to work correctly. The clients are able to ping both servers and no access-lists are configured on the routers. SH3 uses the IP address of R3f0 as its default gateway. Upon powering off SH3 and SH4, the problem goes away even for first connection and everything works normally (even after not connecting for extended periods of time). Which of the following are likely to correct this problem?
