OK.
I reduced it back to 1452.
Then I accessed Bank Leumi. Failed.
Then I applied Ira's (and Tzahi's) iptables rule.
Then I re-accessed Bank Leumi. Voila!

Also, I tried Manor's suggestion, and just omit the mtu, and let ppp
choose its mtu. This succeeded too (tt chose 1500). However, I don't
know if this is a solution, without trying it in an installation where
1452 is the right mtu; It is possible that 1500 is the default, and
selected anytime there is no explicit parameters.

So I guess the rule that Ira and Tzahi suggested, is the solution, and
should be inserted into the HOWTO (which means that we can't avoid
mentioning iptables in that HOWTO...  Currently, there are only
references).
