Enabling Nat-traversal for VPNs on an 837

[chicocouk]

Hi all,

I've been told that IOS 12.3 supports NAT-traversal, encapsulating ESP traffic under UDP 4500. On a pix you need an additional command to enable this, can anyone advise if you need a similar command on an 837?

Any pointers to how to do it, or where to find it in the IOS documentation MUCH appreciated.

Thanks
