IOS versions & vpn traffic help.
Hi,
I've got a question re Cisco site to site VPNs
We have an office in London using a PIX 506E, with two other sites in Germany & the US connecting with 501's. We're trying to install a 3rd site in Singapore using another 501 which is where the problems start.
The 501 in Singapore appears to have different IOS version - 6.3(3) where the others that successfully connect are using 6.3.(5), would the difference in IOS version prevent a successful connection?
Also, does the VPN come up automatically or does it depend in traffic initiating the connection before the link is made.
The reason I'm asking, is that there's currently no-one in Singapore to test the connection, but my config does appear to be correct as I've compared it against the US config.
Thanks
Trevor

you have to have your debugs on. since you are using pre-shared keys, i would confirm that both pix's have the same password

Debugs aren't showing anything at all, what I've read is that debug sends to the serial console port. I'm connecting via remote SSH in the UK, is there another command I need to actually see the output of the debug commands?

Good news! The line came online overnight, so it would appear the first solution answering my question was correct.
Thanks.
Thanks.
