Issue/Introduction
The proxy failed to connect to the network after the upgrade from version 6.7.4 to any version in 6.7.5.
Downgrade back to version 6.7.4, the proxy works fine where it able to connect to the network
The proxy have a static routes installed using an old or non-working IP gateway while on version 6.7.4 like the one below.
10.0.0.0 255.0.0.0 10.11.12.13
Cause
There is a bug in 6.7.4 where the static routes will not get applied properly.
Assuming the working IP gateway is 10.11.12.15 and the routing table on 6.7.4 will show like the below. You are not seeing the static routes in the routing table.
Destination Gateway Flags Refs Use Netif Expire
default 10.11.12.15 UGS 26 2728 1:0
...
However after the upgrade to version 6.7.5, the routing table will show like the following:
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 10.11.12.15 UGS 5 142 1:0
10.0.0.0/8 10.11.12.13 UGS 4 21 1:0
...
Notice the proxy (on 6.7.5) applied the static routes in the routing table causing the proxy failed to connect to the network because the static route overrides the default gateway.
Resolution
Downgrade the proxy to 6.7.4 first and then disable the static route after the confirming that it is not been used or no longer valid.
Then upgrade back the proxy 6.7.5.
