@aalska 我不懂 dns 具体什么意思，我是长城宽带，不知道是不是你说的远端

@Vicer 看了 15L 你贴的路由表，有几个问题想咨询一下
1.请问你的路由表只有这么长吗，我的贴了 3 页，我是应该把你的修改一下直接覆盖还是说你贴的只是需要修改的部分。
2.教程中说“ route 和 no-route 不能同时使用“是什么意思，”#route = 10.10.10.0/255.255.255.0

route = 192.168.0.0/255.255.0.0
route = fef4:db8:1000:1001::/64
Subsets of the routes above that will not be routed by
the server.“这三行我应该删除吗，会有什么影响。

@skylancer 有时间去营业厅问一下

@kendetrics 我的是长城宽带，是二级代理，应该就是你说的非独立公网 IP

@Vicer 谢谢，我晚上回去学习一下。

@Vicer 非常感谢！！

@kendetrics 你说的我不太懂，可以理解为 ip 漂移是正常的吗

@yexm0 对，无论是宽带还是 4g ，每次都变

@Vicer @lenovo 你们好，请帮忙看一下

楼上你好，你的意思是，已经实现了国内网站不走 VPN ，慢是因为 DNS 的原因吗

你好，我也不知道怎么直接回复你，我把 ocserv.conf 文件都复制在上面了，只删去了 tcp 与 udp 的地址，你看有什么错误吗？

# certificate:
# This indicates that all connecting users must present a certificate.
#
# pam[gid-min=1000]:
# This enabled PAM authentication of the user. The gid-min option is used
# by auto-select-group option, in order to select the minimum valid group ID.
#
# plain[passwd=/etc/ocserv/ocpasswd]
# The plain option requires specifying a password file which contains
# entries of the following format.
# "username:groupname1,groupname2:encoded-password"
# One entry must be listed per line, and 'ocpasswd' should be used
# to generate password entries.
#
# radius[config=/etc/radiusclient/radiusclient.conf,groupconfig=true,nas-identifier=name,override-interim-updates=false]:
# The radius option requires specifying freeradius-client configuration
# file. If the groupconfig option is set, then config-per-user will be overriden,
# and all configuration will be read from radius. The 'override-interim-updates' if set to
# true will ignore Acct-Interim-Interval from the server and 'stats-report-time' will be considered.
#
# gssapi[keytab=/etc/key.tab,require-local-user-map=true,tgt-freshness-time=900]
# The gssapi option allows to use authentication methods supported by GSSAPI,
# such as Kerberos tickets with ocserv. It should be best used as an alternative
# to PAM (i.e., have pam in auth and gssapi in enable-auth), to allow users with
# tickets and without tickets to login. The default value for require-local-user-map
# is true. The 'tgt-freshness-time' if set, it would require the TGT tickets presented
# to have been issued within the provided number of seconds. That option is used to
# restrict logins even if the KDC provides long time TGT tickets.
