Hi ,
I have IPSEC configured between local end -Cisco PIX 515E & Remote end
device - Nortel VPN box . Users from Local end use VPN
to access Remote end applciations. But I am facing issues like VPN
disconnections ( 10 users out of 30) intermittently. After i perform clear
all the sessions from Cisco PIX firewall users who are facing problem are
able to connect back to the VPN with out any issues.
My Network :-
user PC ----> Coreswitch--> Netscreen Internal Firewall ----> Cisco PIX
External firewall 6.2OS ver----> ISP Provider -------> Remote end Nortel
VPN.
When we checked with our vendor Cisco theya re suggesting us to enable NAT-T
between our Internal Firewall & Remote VPN to overcome this issue.
Please let us know do we need this option to enable. Also let me know other
possibilities for causing this issue.
Thanks and Regards,
Akber Mirza.
