if i restart katran_server then config data miss take,
if i have to two network interface Wan <--->Lan,how can i configure
like this:
client(172.16.1.100)--->Wan(eth1:172.16.1.101)(vip:172.16.1.200)<--->Lan(eth0:192.168.1.10)--->server(192.168.1.20)

right now examples only includes CLI tools which are configuring katran from cli output.
e.g. (following this guide: https://github.com/facebookincubator/katran/blob/master/EXAMPLE.md) in you scenarion you need to start katran server.
i would assume that you want to use 172.16.1.200 as a VIP. lets say you have a TCP service running on port 80. in this scenario on katran side you need to

  1. configure VIP: ./katran_goclient -A -t 172.16.1.200:80
  2. add backend server to this VIP (e.g. with address 192.168.1.20)
    ./katran_goclient -a -t 172.16.1.200:80 -r 192.168.1.20

after this configuration every packet which katran_server would recive with dst ip 172.16.1.200 port 80 would be encapsulated inside another IP header and resend to server with IP address 192.168.1.20

server w/ ip 192.168.1.20 must have ip 172.16.1.200 assigned to loopback interface (as it would terminate tcp session. all traffic from server will go directly to client (aka katran is handling only ingress packets)

look for "Configuration of forwarding plane" section in EXAMPLE.md (link in prev reply). it shows how to configure and test your topology in greater details

Summary:
After diving in all the build system I found that the first error mentioned in #219 and #220

```
1597 | static_assert(formattable_char, "Mixing character types is disallowed.");
```

Was basically happening while compiling folly, after compiling it by itself I noticed this didn't happened, so I found that there was an issue with the fmt dependencies, removing the one that was downloaded by katran

The issue mentioned in: #221

Was because katran was configured to use C++14 by default, and some of the libraries of folly require C++17, updated our requirements.
