RAS Internal NIC cannot ping dedicated LAN NIC Gateway

-

hello all,

i have configured ras ipv6 server. server has 1 nic. ras interface generated after dialing vpn. ras interface assigned pool 2800:fc11:10:: ipv6 prefix assignment.

the problem ras interface can ping dedicated lan interface servers but  cannot ping lan gateway .

for example:

lan nic gateway : 2800:fc11:20::1

ras interface ip : 2800:fc11:10::1

so ras ip (2800:fc11:10::1) can ping lan servers cannot ping lan gateway (2800:fc11:20::1).

any idea , issue ??

common problem. see if helps:

.

can't ping external network adapter after configuring rras vpn server
 quoted" "... when use routing , remote access server setup wizard configure rras vpn server, input , output filters automatically configured on external network adapter process vpn traffic ..."
"... security reason, rras modify routing table , enable incoming vpn connections no other forward packets on interface except pptp or l2tp traffic."
solution: uncheck box "enable security on selected interface setting uip basic firewall," otherwise if vpn user connects, no 1 in network able access vpn server files, resources, etc, , detrimental if dc, part of reason recommend rras not on dc , on separate server.
on nat tab, selected "public interface connected internet"
